btrfs-progs: tests: add coverage for multiple profiles warning

Browse source 
Several commands now warn about multiple profiles as it is considered a
potentially problematic filesystem state that might need user attention.

 - device delete
 - device add
 - balance pause
 - balance cancel
 - filesystem usage

WARNING: Multiple profiles detected.  See 'man btrfs(5)'.
WARNING: data -> [raid1, single]
