Ticket #47834 - Tombstone_to_glue: if parents are also converted to glue, the target entry's DN must be adjusted.

Description: Previous fix for the ticket #47834 broke the CI test case
47815.

The fix for 47815 removed the addingentry from the entry cache if
SLAPI_PLUGIN_BE_TXN_POST_ADD_FN failed.  The #47834 patch accidentally
deleted the code.

Instead of adding it back, this patch moves the deletion of the entry
from the entry cache to cover both cases SLAPI_PLUGIN_BE_TXN_POST_ADD
_FN successes or fails.
