Add the missing assertions two tests were silently running without

Both ran real code and checked nothing -- Minitest's "missing
assertions" warning has been firing on every run this session.

test_find_or_create_draft_if_draft_exists_and_is_owned_by_user called
the method twice but never checked what came back; now confirms the
second call returns the same draft rather than creating a new one,
and leaves the lock and page count untouched.

test_destroy_a_published_node destroyed a node and loaded the admin
index but never checked the response, unlike its two neighbors
covering the same destroy path (dangling pages, orphaned
occurrences). Added the assert_response :success its own shape
already implied.

No behavior changed -- both were passing before for the same reason
they're passing now, they just weren't proving anything.
