Instead of only checking that an error is reported, check the expected
error message, so that we are sure that this test really covers what
it's supposed to cover.

ERP5 functional tests are failing too often, until we improve the tests or the
code so that we don't have these intermitent failures, restart the failed tests
a bit automatically.

This is of course not good, because it's hiding problems, but the current state
of the test suite with many randomly failing test makes that we sometimes miss
when permanent failures are introduced.

these actions are not ready to be used by end users

Persons created before the introduction of ERP5 Login and user_id will only
have a user_id after migration if they were already user before migration,
otherwise they will not have a user_id and creating assignments and ERP5 Login
for this person creates a user which can not log in the system.

To make it possible for these persons to login anyway, we ensure person has a
user id when validating a login

This is bc67c2c4 again, but with a proxy role
