There's a race condition that may cause a client crash whenever a
video-provider's unmount procedure is run, but its signalling websocket
is undefined. The WS's callback handlers are re-assigned without
checking for the socket's availability, causing an unhandled TypeError.
The WS may be undefined in a couple of scenarios, e.g.: unmouting before
the socket was successfully set up, unmounting while a reconnect is in
place etc.
Check whether the socket exists before accessing it in video-provider's
componentWillUnmount routine.

* fix(bbb-html5): customHeartbeat would not close stale sessions, +
The [disabled by default] custom heartbeat included in Meteor's server
does not end connections when they are considered unhealthy/stale, which
deviates a bit from the default implementation. See:
https://github.com/bigbluebutton/bigbluebutton/pull/11486.
This commit includes a call to the default heartbeat termination timeout
so sockets are correctly cleaned up when the custom heartbeat is
activated. It also adds a customHeartbeatUseDataFrames config to allow
controlling whether the custom heartbeat should use WS data frames as
valid heartbeats as well - this should only be useful for
testing/debugging purposes and the default behavior (true) is
maintained.
As a side note: this change spun off from an investigation where some
problematic networks were triggering periodic client re-connects due to
the default heartbeat failing. Investigation points to the control
frames being put alongside fragmented WS data frames and the server side
failing to recognize the former - which means pong frames would be missed and
the health check would fail. Since the default heartbeat _does not_
account for data frame traffic (eg DDP payloads), it would shut down the
client's WS even though it was healthy.
The custom heartbeat _does_ account for data frames, which mitigates
that scenario and prevents unecessary reconnections.
* fix(bbb-html5): frontend crash due to undefined vars in customHeartbeat
Meteor frontends may crash when customHeartbeat is enabled
due to an undefined access in the heartbeat`s logger.
Add optional chaining to the session props access so it won`t crash and tune down some log levels around that area.
