Avoid creating empty playback metrics

Browse Source 
In some cases we create empty playback metrics with no corresponding
events (e.g. when an app seeks to a new media item and immediately
releases the player). There is no benefit in having completely empty
metrics entries, so it's cleaner to not report them in such cases.
