Ticket 48195 - Slow replication when deleting large quantities of multi-valued attributes
https://fedorahosted.org/389/ticket/48195
In update resoultion for entry deletion, there is still use of valuearray_find() to find an existingvalue to update its csn.
with the fix for ticket #346 there exists slapi_valueset_find() which uses the possibility to do a binary search on the
values.
Fix: do not use valuearray_find
