extended RecordGeneratorTest
fixed RecordGenerator
extended RecordGeneratorTest - added TestCase for auto-generated onDelete=RESTRICT required relation
possible fix for trivial restrict constraint errors - init map for table before adding related records to force delete on this table is called first
added a test case where last commit not works...
fixed delete order of generate records by remember as flat list and delete actual record before all required records (restrict constraints can only appear on that records)
removed dev-TODO
