Incompatible with the dynamic_entity_reference module

Problem/Motivation

If you are using a taxonomy term reference field on your content types provided by the dynamic_entity_reference module, then the referenced entities won't be picked up on the term delete form.

Steps to reproduce

• Install the dynamic_entity_reference
• Add a Dynamic taxonomy reference field to a content type
• Add a node with a referenced term
• Go to delete the term
• Don't see the referenced node

Proposed resolution

The data structure for these fields is slightly different but the basic logic in this module will work. An update to the checks in `prevent_term_delete_form_alter` will make this module work for both.

Will get a patch up and over as the site I'm working on has a mix of taxonomy reference fields.

Cheers
