[FIX] base: fix xml_id creation of custom groups

Steps to reproduce:
- Go to "Settings / Users & Companies / Groups"
- Create a group (e.g. Group X)
- Go to "Settings / Technical / Actions / Server Actions"
- Create a server action:
  * Model: [any] (e.g. Contact)
  * Action To Do: Execute Python Code
  * Python Code: [any]
  * Security: Group X
- Create contextual action
- Connect with a non-admin user (i.e. Marc Demo)
- Open Contacts app

=> An Access Error is raised:
"You are not allowed to create 'Model Data' (ir.model.data) records.

This operation is allowed for the following groups:
	- Administration/Access Rights

Contact your administrator to request access if necessary."

Cause:
When the group is created, its external identifier is not created directly.
When opening Contacts app, the list of authorized actions is evaluated.
During the process, "_ensure_xml_id" is called on the groups configured on
the actions to create the missing external identifiers.
However, the current user (i.e. Marc Demo) has not the rights to create an
external identifier.
