onCreate was firing an async call to updateList with a 250ms delay to wait for the view to be created.
It's wrong (there no garanty that the view will be created at the end of the delay),
and totaly useless, since we now call updateList in onViewCreated

Also remove the possibility to hide the player because it's confusing
from a user perspective.

Otherwise, scanning "/" can take forever...
