Fix applied to ease user experience after the user_id field removal
for performance in 509b4cad.
This is a simple fix to allow users to have ready filters available
instead of having to enter them. This is especially helpful because,
for performance reason, when no domain is selected, no user will be
added, even though the widget on the webclient shows that all user
records are matched and will be added.
This is why [("active", "=", True)] is also added, allowing to simply
remove the "internal user" rule to really have all users if desired.
