Seek bar issues

[jonasburian]

This fixes issues of the seek bar, mentioned in #4915

• Buffering indicator drawn incorrectly
• Not refreshing divider positions with duration change
• Seeking to first chapter not reliable

I'm not sure about the third one. In my testing, the seeking worked every time (the same as via the chapters page). The only thing that was a bit strange is the highlighting, but I'm not sure (yet) how to solve that.

You are right - I was fooled by a display glitch. Jumping itself actually works.

When pressing the second and third chapter's section on my test feed, the thumb jumps to the beginning of that chapter immediately. When pressing the first one, the thumb stays where it is, highlights the chapter that was playing last and only gets set to the correct position on the next position update event. Hmm. Not sure why this happens.
