Taxonomy manager should fire hook_entity_delete when deleting terms

As in all base entity modules, this module should also fire hook_entity_delete when deleting terms.

Here is an example in taxonomy_term_delete() on taxonomy.module:

...

if ($term = taxonomy_term_load($tid)) {
  db_delete('taxonomy_term_data')->condition('tid', $tid)->execute();
  db_delete('taxonomy_term_hierarchy')->condition('tid', $tid)->execute();

  field_attach_delete('taxonomy_term', $term);
  module_invoke_all('taxonomy_term_delete', $term);
  module_invoke_all('entity_delete', $term, 'taxonomy_term'); // HERE IS WHAT THIS MODULE IS MISSING.
  taxonomy_terms_static_reset();
}

...
