This also removes the use of the useLivekitRoom hook: we had reached
the point where the only thing it was actually doing was disconnecting,
so we now do that in the onClick handler for the leave button (I don't
think we need to disconnect on unmount?). It was otherwise just getting in
the way and causing tracks to be enabled/disabled when we didn't want them
to be. This also removes the need for the blockAudio code.
Fixes https://github.com/vector-im/element-call/issues/1413
This upgrade came with a number of new lints that needed to be fixed across the code base. Primarily: explicit return types on functions, and explicit visibility modifiers on class members.
See comments. I'm not very happy with how this code bounces state in and out of different hooks and useEffect blocks, but as a quick fix this should work.
This was causing an extra reconnect cycle when the call was first
joined because it thought the previous SFU config was valid. This was
probably causing some client to fail to connect at all.
