Fixed an issue about connecting wallets (#422)

Closes # #381


### What

There is a issue related to incorrect handling of the Taho wallet in the
`@web3-onboard/taho` library. Let's fix this with a patch file. The
solution is still not ideal because it does not catch the change of
which wallet is switched on. This means that when we install the Taho
wallet we have to refresh the page to see that the wallet has been
installed. I think this solution is enough at the moment. Let's solve
this problem in #423.


### Testing

**When MetaMask is installed**

- [ ]  Try connecting when the wallet is the default
- [ ]  Try connecting when the wallet is not the default

**When MetaMask is'n installed**

- [ ] Try connecting when the wallet is the default
- [ ] Try connecting when the wallet is not the default

**When Taho isn't installed but MetaMask it is**

- [ ] There is no connection possible. The user receives the correct
message.
