> An offline split parent region can be assigned by using 'assign' from shell.
> This may trigger a compaction on the split parent region that should be offline, breaking the references of the two daughters.
> The easy way to test this is:
>  * disable compactions
>  * create a table and insert some row
>  * split
>  * shutdown the master (otherwise there's a state checked inside the AssignmentManager)
>  * start the master
>  * assign the region marked as OFFLINE => true, SPLIT => true (the compaction on region startup will probably break the reference of the two  daughters)
