Simon Charette 13922580cc Refs #30581 -- Made unattached UniqueConstraint(fields) validation testable.
The logic allowing UniqueConstraint(fields).validate to preserve backward
compatiblity with Model.unique_error_message failed to account for cases where
the constraint might not be attached to a model which is a common pattern
during testing.

This changes allows for arbitrary UniqueConstraint(fields) to be tested in
isolation without requiring actual models backing them up.
