This test can lead to a deadlock,
when trying to drop the constraint on `ir_model_fields`
during the registry loading,
as the test opens a second cursor in addition
to the cursor used for the registry loading,
and drop a constraint on a table which is being read by
the registry loading (`ir_model_fields`), leading to the deadlock.
See screenshot in the PR for illustration.
This has been detected in the runbot nightly builds,
which were pending indefinitely because of that deadlock.
To reproduce, just init a database with `-i base`,
then restart the server with just `--test-tags .test_add_field_valid`.
To avoid to drop the constraint during the registry loading,
and hence to avoid the deadlock,
tag the test as `post_install`.
That way, the test is executed after the registry is loaded,
not during, and the constraint can be drop safely, not leading to a deadlock.
