LP1908766 Bootstrap OPAC: Lost ability to have notes in lists.

Fixes the note functionality in the Bootstrap Opac lists.
The button definition needed both the name 'save_notes' and an arbitrary value.

To test:
1. Create a list in the bootstrap opac and add a couple of titles to the list.
2. View the list and try to add a note to one of the items in the list.
3. This should fail with an error.
4. Apply the patch.
5. Try to add a note. It should now be successful.
6. Try to edit the note.  This should also succeed.
