This should be used when the hash is previously known and can't
be calculated from the relations anymore.
The only use case for this is package resurrection. We're
planning on getting rid of package resurrection, and this code
can be removed when that is done.

@param relation_tuple: A tuple, (name, version, relation). version
and relation can be the empty string, if the relation is on a
name only.
