Rob Crittenden 9b73da1d54 Refresh state data before removing the dirsrv user, fixes uninstall. 
The state is read only at initialization time. This works ok when
individual services remove their state data but when worked upon again
at the top-level it still has the full state in memory, so when the
state file is re-written all of the data that was removed is re-added.
