Bug 11955: Remove spaces in empty indicators when linking an authority to a biblio record.

This patch removes spaces in indicators which are imported when we link an
authority to a biblio record. The spaces made the indicators harder to edit
after the linking, because we had to delete the superfluous space character
before a new value could be entered.

To test:
1. Open some authority on editor, save with empty indicators.
   They are saved as ind1=" " ind2=" " on auth_header tables, with spaces
2. Edit some record, link some tag with previous auth,
   indicators now have a space on it (or ind1 at last)
3. Apply the patch
4. repeat 2, space is gone
