[IMP] util.records.uninstall_module: use remove_group

In `uninstall_module` it is not using `remove_group` for
records from model `res.groups` which leads to face
**psycopg2.errors.ForeignKeyViolation** while removing the records
from `res.groups`, if the group has relation
with _**ondelete=restrict**_.

closes #174
