storage: Warning about attempt to mount loop device

After running sudo py.test-3 in the /vagrant folder, when I start FreedomBox I get this warning:

    INFO plinth.modules.storage.udisks2 New filesystem found:  /dev/loop0p1
    INFO plinth.modules.storage.udisks2 Auto-mounting device:  /dev/loop0p1

Should it ignore loop devices for auto-mount?
