We cannot look up the name as the meeting is left and data has been cleaned up already.
The value is coming from ljm and the reported actor: JitsiParticipant.

Moving to breakout room and back in main room do not fire videoConferenceLeft events.
And the videoConferenceJoined was reporting wrong conference name on join.

Signals that the bridge channel is open. It may take a few ms to get established
after the conference join, so applications might be interested in using it once
ready.

- update lib-jitsi-meet to version with support for replacing participant

Up until now we relied on implicit loading of middlewares and reducers, through
having imports in each feature's index.js.

This leads to many complex import cycles which result in (sometimes) hard to fix
bugs in addition to (often) breaking mobile because a web-only feature gets
imported on mobile too, thanks to the implicit loading.

This PR changes that to make the process explicit. Both middlewares and reducers
are imported in a single place, the app entrypoint. They have been divided into
3 categories: any, web and native, which represent each of the platforms
  respectively.

Ideally no feature should have an index.js exporting actions, action types and
components, but that's a larger ordeal, so this is just the first step in
getting there. In order to both set example and avoid large cycles the app
feature has been refactored to not have an idex.js itself.

* ref(feedback): emit api feedback submitted on completion

Compared to firing the event on submission because
the submission ajax will not be completed at that
time..

* squash: update package.json

- Use actions to notify the rest of the app that
  a mic or camera error has occurred
- Use middleware to respond to those notifications
  of errors by showing in-app notifications and
  notifying the external api
