Video is paused while play/pause button shows "paused" icon.

Steps to reporduce:

1. Add two Chewie widgets to the same screen (in my case they were pointed at two different vimeo hls streams).
2. Press play on one Chewie player.
3. Then press play on the other Chewie player.

Observed behaviour:
The first video stops playing, and enters into a paused state. The play/pause button displays a pause icon. This is inconsistent, as the user would expect a paused video to display a play button. The user can then press the pause button, which then results in the button changing from pause to play icon, and the video stays paused. At this point the video state and the play/pause button state is corrected. The user can then press play button to start the video playing again.

Expected Behaviour:
When the user starts the second video, and the first video pauses, the first video's play/pause button changes from a pause icon to a play icon.
