Don't swallow PlayerStatusEvent if media changed (#8554)

### Description

Don't swallow PlayerStatusEvent if media changed. We only checked the
status, but if we directly started a new episode without going through
pause/play, we skipped sending the PlayerStatusEvent incorrectly.

Closes #8548
Closes #8516
Closes #8530
