Accept Connection Invitation Behavior
During the acceptance of an invitation url, the service gives successfull feedback, even when the records in the background are not stored in the DB (in cause of authentication problems). The only way to find this out is to search manually for the connection which gives the exception that the DB is not accessible.
How should it be?
When a connection is accepted and the database is not able to store it, a 400 exception must come back.
