I'm guessing this was a bug as it doesn't make sense that we would set paused to true if the video is playing, and not paused if it wasn't. I believe this is a safe change since we only release the player when the app is closing or we detach (which is going away shortly). We need this since we release the player in order to apply new bufferConfig settings.
