[gnome-music/wip/mschraal/file-exists-async: 4/8] Reset I/O priorities

[Marinus Schraal <mschraal src gnome org>]

commit 951820c3961e47e3098ce76110e07d6e4d07b130
Author: Marinus Schraal <mschraal gnome org>

    Reset I/O priorities
    
    Previously Music would set most async I/O priorities as low as possible
    to give the main thread space. With recent async improvements, the low
    priorities make less sense.
    
    Reset most I/O priorities to default. Make the albumsview on
    demand cover loading priority a little higher as it is the main view.
