Reproduction steps

Use the horologist media-sample.

MediaController -> MediaSession -> WearConfiguredPlayer -> ExoPlayer.

WearConfiguredPlayer will open the Bluetooth fragment if no headphones are connected, ignoring the play() command.
If you close the fragment without selecting headphones, you end up on the player screen. Hitting play again will open the fragment again. After closing the fragment again, the player State is out of sync.

Workaround is to fire an event - see PR in https://github.com/google/horologist/pull/558/files

Expected result

MediaController - playWhenReady = true
ExoPlayer - playWhenReady = false

Actual result

MediaController - playWhenReady = false
ExoPlayer - playWhenReady = false
