* Improve accessibility and testability of Tooltip
Adding a role to Tooltip was motivated by React Testing Library's
reliance on accessibility-related attributes to locate elements.
* Make the ReadyWatchingStore constructor safer
The ReadyWatchingStore constructor previously had a chance to
immediately call onReady, which was dangerous because it was potentially
calling the derived class's onReady at a point when the derived class
hadn't even finished construction yet. In normal usage, I guess this
never was a problem, but it was causing some of the tests I was writing
to crash. This is solved by separating out the onReady call into a start
method.
* Rename 1:1 call components to 'LegacyCall'
to reflect the fact that they're slated for removal, and to not clash
with the new Call code.
* Refactor VideoChannelStore into Call and CallStore
Call is an abstract class that currently only has a Jitsi
implementation, but this will make it easy to later add an Element Call
implementation.
* Remove WidgetReady, ClientReady, and ForceHangupCall hacks
These are no longer used by the new Jitsi call implementation, and can
be removed.
* yarn i18n
* Delete call map entries instead of inserting nulls
* Allow multiple active calls and consolidate call listeners
* Fix a race condition when creating a video room
* Un-hardcode the media device fallback labels
* Apply misc code review fixes
* yarn i18n
* Disconnect from calls more politely on logout
* Fix some strict mode errors
* Fix another updateRoom race condition
* Remove blank header from video room view frame
* Add video room option to space context menu
* Remove duplicate tooltips from face piles
* Factor RoomInfoLine out of SpaceRoomView
* Factor RoomPreviewCard out of SpaceRoomView
* Adapt RoomPreviewCard for video rooms
* "New video room" → "Video room"
* Add comment about unused cases in RoomPreviewCard
* Make widgets in video rooms mutable again to de-risk future upgrades
* Ensure that the video channel exists when mounting VideoRoomView
