Using anything non-serializable for action types is discouraged:
https://redux.js.org/faq/actions#actions

In fact, this is the Flow definition for dispatching actions:

declare export type DispatchAPI<A> = (action: A) => A;
declare export type Dispatch<A: { type: $Subtype<string> }> = DispatchAPI<A>;

Note how the `type` field is defined as a subtype of string, which Symbol isn’t.

* fix(local-recording): allow config override to enable

Config overrides are not set until some time after
APP_WILL_MOUNT has completed and not in the same execution
context as when APP_WILL_MOUNT is called. So instead
choose recording controller initialization at a later time.
The time chosen is after conference join because the
controller needs the conference instance to work.

* remove redundant conditional check

move duplicate code from WavAdapter and FlacAdapter to a base class

fix Promise in setMuted

When newly joined clients register for XMPP events upon
CONFERENCE_JOINED, those events that is carried by presence (e.g. START_COMMAND) was
already fired.
Temporary solution is to let the client send a ping message after
registering XMPP event listeners. The moderator will respond with
pong, which forces the presence to be resent.

Situation when the RecordingController receives a new START_COMMAND
while it is initializing the recording adapter for the previous
START_COMMAND.
