Eloy Lafuente (stronk7) 07a069f1c0 MDL-50063 unittests: Remove some unnecesary gc_collect_cycles()
Now backup and restore operations free logger resources calling
to the destroy() method. This commit ensures:

1) That gc_collect_cycles() is not used anymore in backup-related tests.
2) That all backup and restore controllers in test do always call
   to the detroy() method.
3) Some unset() calls, needed to make gc_collect_cycles() are not used
   anymore.
