Newpipe: Don't show overlay after resuming from buffering

[Knowbody42]

If I'm watching a video and it needs to buffer, the overlay (play/pause, seek bar) keeps appearing over the top of the video after it resumes.
It's annoying having to press the screen to make it disappear.

This a long time annoyance for me, I just didn't have the time to improve it.

I'll try to in the next few days.

@mauriciocolli If you wouldn't mind, I'll take care of this issue as part of #1147 since they are closely related.

Ok, it's all yours.
