Bug 11216 - Patron modification creates indefinite manual restriction

Editing partron data results in unintended adding of indefinite manual
restriction to it. Reason for it is hidden field add_debarment which
is wrongly initialized to 1 instead of 0. Also JavaScript code seems
to want to toggle checkbox, and sice this field is hidden correct
approach would be to change it's value to 1.

Test scenario:

1. edit patron data
2. verify that debarrment is wrongly added
3. remove debarrment
3. apply this patch
4. edit patron again
5. verify that debarrment wasn't added
6. intentionally add debarrment and verify that it's saved
7. add debarment, enter something in comment but press cancel
   and verify that debarment isn't added
