Settings: Fix app ops details not displaying permissions under certain
conditions.

If there's a permission that is not granted, the loop is aborted instead
of just skipping said permission.

Settings: Make app ops more usable

gets rid of the arbitrary categories,
shows all operations, not just the ones that were in use

operations != permissions. app ops is not permission management

PS2: Hide the tabstrip as we only have one category
