Bench: fix hardware decoding tests

To force opengl es, we have to restart the player, some changes in
vlc-android made the method previously used restart the whole activity
which would yield focus back to the benchmark app.
This adds a "soft" restart of the video player, without restarting
VideoPlayerActivity.
