Though still make sure metadata is updated after the thumbnail is loaded.
This fixes the wrong seekbar properties (duration and current position) being shown in the notification sometimes.
A while ago NewPipe called the metadata update function very often, so checks were needed to ensure not wasting time updating metadata if it were already up to date. Now, instead, the metadata update function is called exactly when needed, i.e. when metadata changes, so such checks are not needed anymore (and were probably also a little resource-heavy).
The thumbnail was not being updated in the media session metadata after it was loaded, since there was no metadata update in that case, only a notification update.
