cubicweb #13117472 [dataimport] order of ExtEntities should be irrelevant [validation pending]

Currently, given a = ExtEntity A with a relation to 'B' and b = ExtEntity B a call to import_entities([a,b]) will fail.

It should not be the case and the order of the entities in the list passed to import should not be an issue when one refers the other.
