Fixes two bugs, one was definitely happening, and 2nd one that is causing undefined behavior and may work only in some std implementations - VideoPlayer would attempt to access subtitles widget after VideoPlayer itself was destroyed in onPlaybackFinished call - std::function was destroyed from a function that is being called by it. Replaced with 1-method interface to avoid usage of std::function in this scenario
