- Better loading of translations using suspense.

Issue: GREG-72

Before this commit, the userinfo endpoint would fail if the user
did not have a person object connected to their GregUserProfile. We now
check that this is the case before checking the person objects roles.

If the notification to be published is regarding a Role, Identity or
Consent object, we now add the 'data' field with a 'person_id' key where
the value is the id of the Person connected to the Role, Identity or
Consent.
