edi_endpoint: temp fix for tests

I don't know why but  when test_edi_endpoint runs before these tests
the rollback of the exception catched within the test `test_archive_check`
make the controller lookup fail.
Since the whole routing registry machinery is going to be refactored
in OCA/edi#633
let's survive w/ this forced registration for now.
