Tables in test db are not created for models with app_label

[kosdmit]

I use --no-migrations option to create a test database by inspecting all models. This usually works well, but I got a problem with django models that have an app_label meta attr. Such models are ignored and do not create automatically.

Model for example:

class SAPDepartment(models.Model):
    class Meta:
        app_label = 'structure'

    sap_name = models.CharField(max_length=150, null=False, blank=False)
    sap_id = models.IntegerField()
    up_dep = models.ForeignKey('self', related_name='low_dep', on_delete=models.SET_NULL, null=True)

Tables list if we do not use app_label (sapdepartment table exists):

test_procurement_db=# \dt
                         List of relations
 Schema |                 Name                  | Type  |  Owner
--------+---------------------------------------+-------+----------
...
 public | django_content_type                   | table | postgres
 public | django_session                        | table | postgres
 public | info_db_sapdepartment                 | table | postgres
 public | info_db_sapemployee                   | table | postgres
 public | material_analogue_employee            | table | postgres
...
(27 rows)
