[Android] [VideoPlayer] When one makes a seek to a non-zero frame and then immediately a seek to 0, Video freezes for a while

Video

-

How to reproduce:
1. Open the attached project
2. Build and run WebmSync scene on Android device
3. When video starts playing Press Forward button few times (also you can switch to another video, one is mp4 another one webm)
4. Then press Backward button 5 times quickly
Result: Video freezes for ~6 seconds and then continues playing
When one makes a seek to a non-zero frame (e.g. 475) and then a seek to 0 immediately without waiting for the seek to complete. Internally, we think the seek has already completed (because the seek to 475 has not yet been completed by pulling one frame) and we optimize it out. What this means is that the media stays at 475 while waiting for the VideoPlayer to be at 476 and that is why video freezes for some time.

    Resolution Note (fix version 2019.3):

    Better logic to distinguish between seek to 0 and seek to current position in contexts where the current position is not yet established.
