Resolves: #457156

Summary: GER: allow GER for non-existing entries (phase 2) (comment #3)
Description: get the target dn from the pblock and add it to the template entry
dn if available.  Plus a memory leak was found and fixed at the same time.
Following the suggestion from Nathan, the "dummy" attributes are replaced with
"(template_attribute)".
