Revert "[catalogue] cta/CTA#951 Fixed"
This reverts commit 7c6609d2. The orginal commit is being reverted because it intentionally forced the "list contents of a tape" query to use indicies by replacing table joins with sub-queries. These sub-queuries unfortunately turned out to be slower than the original query when it was executed in a "clean" environment and the database live memory cache was cold. By "clean" environment I mean one without PARALLEL enabled on the following two tables: ARCHIVE_FILE TAPE_FILE PARALLEL is enabled on these two tables when a CASTOR to CTA migration takes place. It was left in place with the hope that it would not interferre with the day to day running of CTA. This has now been proven to not be the case.
