Bug Description:
A large valueset (more than 10 values) manages a sorted array of values.
replication purges old values from a valueset (valueset_array_purge). If it purges all the values
the valueset is freed (slapi_valueset_done).
A problem is that the counter of values, in the valueset, is still reflecting the initial number
of values (before the purge). When the valueset is freed (because empty) a safety checking
detects incoherent values based on the wrong counter.
Fix Description:
When all the values have been purge reset the counter before freeing the valueset
