The LDB_ERR_ENTRY_ALREADY_EXISTS error code is detected in repl_meta_data as indicating
that the DN exists, and that a conflict record should be created.
This is really a constraint violation, not a duplicate record.

With the GUID index option, the values in the index result list may
not be a DN but the objectGUID. We look up the @IDXDN index with the
case-folded DN to get that if required.
We re-use the code from the SCOPE_BASE search do avoid duplication
and for reliablity.

This will allow use of a GUID TDB key in the future. While ltdb_search_base()
might be marginally slower than tdb_exists(), no allocation is done for the
attributes or DN, and renmaes are not a very common operation.
This allows a check if the target DN exists even when the direct DN -> key
link is broken.
