-----------------------------------------------------------
RSGroupAdminEndPoint#postCreateTable() calls assignTableToGroup() and table
state is checked before moving it.
The TableStateNotFoundException is thrown by TableStateManager#getTableState(),
but caught byTableStateManager#isTableState(). So it does not abort the program.
It might not a big deal since the exception being caught already, but the point
is that the logic is not correct.
