solve this issue. Assuming that I loop through all fields present in the
base model, check if they're present in the inherited model, and if there
are any such fields present, append `base_app_label, base_name,
field_name, False` to `dependencies`, how would adjusting
`check_dependency` able to reorder the migrations?
