FIX: Bug with permanent delete modal (#18825)

Repro steps:
- enable permanent deletes (via hidden site setting)
- set `min_topic_views_for_delete_confirm` to 0

When permanently deleting, the delete confirm modal is shown (for a
second time) and it doesn't pass the `force_destroy` parameter to the
request and the action results in a 422 error (i.e. can't perma-delete).

This change skips showing the confirm modal when perma-deleting given
that it has already been show on the first delete action.
