Song progress seeker doesn't move

[compliment]

Please consider making a Pull Request if you are capable of doing so.

App Version:

v1.5

Affected Device(s):

Android 8.1

Describe the Bug:

Seekbar/ progressbar doesn't move at all, although it does respond to time seeking. To Reproduce:

1. Play a song

[costular]

I think we should update current progress when user start tracking as well, not only onProgressChanged().
