Fix #[foreign_key] / #[referenced_by] compile checks to be table-pair specific (#117)

* Initial plan

* Fix foreign_key/referenced_by compile checks to include both table names

The compile error check identifiers previously used `this_table` as a
suffix, which meant that having ANY foreign_key or referenced_by
attribute on a table would satisfy the check, even if it referenced a
different table. Now the identifiers include both the referenced and
referencing table names, ensuring compile errors are correctly raised
when specific table pairs are missing their attributes.
