Bug 24305: (QA follow-up) Strip table name in [[table.field|alias]]

Bug 24305: (QA follow-up) Strip table name in [[table.field|alias]]

When you would use the construct, you wont have batch features unless
we strip the table name. This is consistent with the $sth->{NAME} used
to fill the headers by default.

Test plan:
Use [[items.biblionumber|bibno]] instead of items.biblionumber in a
reporting query.
