[autoform] fix appearance of link to add inlined creation form
On entity creation, if there are some local permissions on the relation,
we have no way of checking them since neither the subject nor the object
of the relation exists yet. In such a case, we should add the link by
default, for consistency (see other places where we use
`may_have_permission`).
