Bug 15682 - Merging records from cataloguing search only allows to merge 2 records

To test:
1 - Perform a cataloging search
2 - Attempt to merge 0 results - should fail
3 - Attempt to merge 1 resutls - should fail
4 - Attempt to merge 2 results - should succeed
5 - Attempt to merge 3 results - should succeed
6 - Test any other amount of records and if more than 1 it should
succeed

**Note: On shelves.pl you can merge a single record.  I think that is
incorrect so made this only work for 2. Will add a followup to fix
shelves.pl
