Enable erp5 login user manager in post_upgrade

I just simulated an upgrade for an ERP5 running a version from before !185,  `ERP5UserManager Non Existence_constraint` properly disabled old `acl_users/erp5_users` and migrated all persons, but  `ERP5UserLoginManager Existence_constraint` did not activate `acl_users/erp5_login_users`.

This is because  `ERP5UserLoginManager Existence_constraint` is registered as a **pre-upgrade** constraint, but with my upgrade scenario, pre-upgrade constraint are installed too late. 

The upgrade scenario was:

 1. install new ERP5 SR on slapos
 2. manually install new versions of  erp5_upgrader and customer_configuration_upgrader business template
 3. run upgrade ( sense then fix on portal_alarms/promise_check_upgrade )

During step 3, when pre-upgrade constraints are executed, erp5_base is not installed yet, so  `ERP5UserLoginManager Existence_constraint` can not run because it's not installed yet. 

My suggestion is to change it to a post-upgrade constraint.

If I understand correctly and my upgrade scenario is really the supported one, it means we can only have pre-upgrade constraints in erp5_upgrader.

( I also fix a meaningless typo in the same code)
