Bug 11163: display correct itemtype usage count when deleting an itemtype

Wrong usage of UNION instead of UNION ALL prevented the count to match
the expected value.

Steps to reproduce:
- Create an itemtype.
- Create some biblios setting the created itemtype at biblio level.
- Create some items setting the created itemtype on them.
- Try to delete the itemtype in Home > Administration > Item types, the
count is 1 and doesn't match the expected result.
