I found this issue while working on #25172. The ArrayField uses the check
framework to perform backend specific checks on the `base_field` instance,
but doesn't set the `model` attribute on it.
Since the backend specific field tests will use the model to route to the
appropriate db connection, we need to have the model set on the
`base_field` instance too.

Here's the PR in github with the proposed fix:

Refs #25226 -- Cloned ArrayField.base_field on deconstruction.

This prevents the base_field from sharing attributes with the one used
during migrations.
