Unfriendly error message when unauthenticated

[vosdev]

When I visit the dashboard with a deep url like such:
https://lxd.example.com/containers.php?remote=1&project=default

I get a javascript popup stating:

Unable to connect to remote host. HTTP status code: undefined

Followed by a redirect to the login page.

I think it's more friendly to have the redirect happen right away and not show the pop-up

I am seeing that Firefox is doing the redirect automatically on my setup, but Chrome is giving me this message. I am guessing that you were using Chrome. I will look at updating this.
