Error adding data using create

register_tortoise uses the config configuration to report an error when adding data

models：
`

Reproduce the provided Group.create call with the register_tortoise configuration, then inspect tortoise/models.py and tortoise/backends/base/executor.py at the traceback locations. Confirm why the base query lacks the reported method and identify a regression test covering creation with this configuration; done means the insert completes without the AttributeError.
