Podcast was playing even though the UI said it wasn't, and the audio doubled-up when I pressed play

### Description

I launched the app (I believe it was no longer in memory by that point) , and pressed play on the currently in-progress episode, which was not downloaded, but was being streamed. After a few seconds it hadn't started playing yet, so I pressed the play button again (it may have said it was playing already, in which case I presumably tapped twice, once to pause and once to play again).

I'm don't remember the exact timing of everything or exactly what I pressed when, but the app ended up playing two instances of the episode, offset a bit from each other. Pressing pause would pause one instance while the other kept playing. The playback controls in the notification shade behaved the same way as the ones in the app. To fix this state, I had to swipe away the app from the app switcher.

### Step-by-step reproduction instructions

I don't have easily reproducible steps, unfortunately

Start by investigating playback after launching the app with a non-downloaded episode, then pressing play repeatedly while streaming. Compare the in-app and notification-shade controls; done means one playback instance remains active and pause controls stop it consistently.
