Chatrix peeking w/ guest account

[ashfame]

This draft PR (not meant for merge) highlights the differences needed in Chatrix to make guest account peeking work.

This would require more changes than current's peeking PR to Hydrogen (Automattic/hydrogen-web#7) So this branch in Chatrix uses the linked branch in Hydrogen as its dependency for Hydrogen.

To run: Pull the branch and don't forget to yarn install and yarn build

I edited your description so that it contains Automattic/hydrogen-web#7 in verbatim, thus Github can create a link into that PR.

The branch is now functional except the error that you see on the top ruining it asthetically. Guest user session isn't allowed to create a filter, hence this error.

This brings us to the question of how does Hydrogen want to treat guest user session different than a regular one, and how is that best done, which is what I am currently exploring. I would prefer to do it within Chatrix for now, if possible, before we get to the topic of how does "guest user session" look like in Hydrogen.

With more changes done in Automattic/hydrogen-web#7 this is now functional without the error in the screenshot above. Sync runs for guest user session and should, for cases when guest user session is used to join a room.

Here are some issues I found while trying this:

1. Sometimes chatrix doesn't load and the block will say Something went wrong, this.session.isGuest is not a function

2. Sometimes some assets fail to load, CSS or fonts, though this could be unrelated to this PR (though I don't think I had experienced it before)

3. Chatrix doesn't seem to remember anymore which session is open. After logging in as guest, then logging with my regular account, I will have two sessions in the session picker. If I open one session, then refresh the page, I will go back to the session picker.

1. Sometimes chatrix doesn't load and the block will say Something went wrong, this.session.isGuest is not a function

This issue has been fixed!

2. Sometimes some assets fail to load, CSS or fonts, though this could be unrelated to this PR (though I don't think I had experienced it before)

I haven't encountered this issue even once so need to reproduce it before I can debug it.

3. Chatrix doesn't seem to remember anymore which session is open.

Remembering last session is part of the "last url restoring" functionality which is now disabled for single room mode. We also talked about how its safe to assume for Chatrix context to not have multiple sessions. Have you identified a use case which justifies support for multiple sessions in a single Chatrix instance? If so, can you help me with the user story for it?

[ashfame]

@psrpinto For point 3 above, if you have indeed identified the need for multiple sessions in a single Chatrix instance opposed to our assumption, can you please file an issue with the user story? We can handle that in a follow up PR. For now, I am taking this PR forward ✌️

2. Sometimes some assets fail to load
   I haven't encountered this issue

Maybe this was related to the this.session.isGuest is not a function error. Please ignore.

3. Chatrix doesn't seem to remember anymore which session is open.

I opened #200 to track this.
