Fix DRSUAPI replication test - NET-API-BECOME-DC.

Fix DRSUAPI replication test - NET-API-BECOME-DC.

The main change here is to work with the current module stack,
replacing only the objectGUID module, rather than a number of modules.

However, two changes were key:
 - Fixing a typo search_req->handle -> change_req->handle
 - Allowing an error of NO_SUCH_OBJECT - it is quite valid
   for the object not to exist when being replicated in.

Other small changes were required to the ejs provision to match
changes in that code.
