Bug 33513: Remove whitespace in batch report lists

Bug 32368 added whitespaces, remove them.

To test:
 1 - Create a report like:
    SELECT biblionumber FROM biblio
 2 - Run it
 3 - Try the various options from the 'Batch operations' button
 4 - The operations don't find the biblios
 5 - Create a report like:
    SELECT cardnumber FROM borrowers
 6 - Run it
 7 - Test the batch operations
 8 - They fail
 9 - Apply patch
10 - Run each report again and test batch operations
11 - They work!
