[CWEP002] properly handle serialization of computed attributes
Until this cset, only serialization of computed attribute's formula was
handled (thanks to the relation definition's properties dict).
We now:
* properly serialize/deserialize attribute's formula
* test first if the database has been migrated and contains related
column or not
