Fix Jira access when granting the Support service

Steps to reproduce:

1. Go to Account Management
2. Affect a user to the Support service
3. Observe in the backend that the user has been added to the Support service document => correct
4. But the user has not been added to the group Okta Jira and therefore the Jira app is not added to the Okta profile

Expected behavior: adding a user to the Support service adds the user to the "Okta Jira" group in Nuxeo Connect
