Fix: Activate user deactivated by Invite job (RTC-42719)

When user is removed from invited group in AAD, he is deactivated in User Management. When he is added again to one of invited groups, he is activated, with both (if specified) added roles and existing before deactivation. 

For now, if user had some roles assigned, for instance via auto-provisioning, then even when he is deactivated by being removed from invited group, he keeps these roles. Then when added to different group and being activated, these roles are still assigned. This mechanism is planned to be changed during development of assigning roles to store groups in invite job.
