This module allows any user to get special permissions to be able to
deduplicate contacts, instead of just giving them to a sale manager with
settings permissions.
The new permissions allow the user to deduplicate:
- *Manually*.
- *Automatically* (dangerous).
- *Without restrictions* (more dangerous).
Beware what you do! 😯
If merging 2 contacts, one with reference, and another without, and being the target
one the contact without reference, the constraint is raised as the reference value
is copied before unlinking the other contact.
We avoid it disabling the constraint when merging.
