LP1920039-Bootstrap Opac: More Details button doesn't change on use.

The 'More Details' button in a bib record in the Bootstrap Opac should change
to say 'Less Details' when pressed.  This patch fixes that behavior.

To Test.
1. Go to a bib record in the boostrap opac.
2. Press "More Details"
3. Notice the button still displays "More Details"
4. Apply the patch and repeat.
5. The button should now toggle between "More Details" and "Less Details"
