list_content call never raises DataIdentifierNotFound

[bari12]

Description

Due to the change to the new SQLAlchemy2 syntax with scalars, this query will never raise the exception.DataIdentifierNotFound, but instead just return an empty scalar.

Additional Information

Best would probably be to join with did table and check if the did exists in the first place. Another option would be, if no result is found, to check for a dataidentifier then.
