Connection robustness improvements (#813)

* Clear heartbeat and queue when disconnected

* Give clearer error in case configure fails due to a lost connection. Used to throw 'Packet does not exist'

* If the queue processing error is due to a lost connection, throw it instead of looping endlessly

* In case we send a disconnection event we don't need to also throw

* Catch heartbeat errors

* Also handle invalid state errors

* Handle socket timeouts

* Log heartbeat failures

* Make linter happy

* Transform stream being a singleton prevented reconnection attempts

* Adapt tests to not using singleton

* Aborting already ends the connection
