If user tries to delete a glossary (where a term is assigned) a second time, the dialog box goes into endless loading animation

Steps:

1. Create glossary and then term
2. Assign term to entity
3. Delete glossary and click 'ok'
4. You will get an error stating that the term is assigned to an entity.
5. Again try to delete the glossary and click OK

This time the dialog box goes into an endless animation, and only on browser refresh can you escape it.
