Prevent Django ManyToManyField from being imported through sortedm2m

[daynemay]

At my workplace, we recently uncovered a bug (in our codebase) where we had defined a field in models.py as a SortedManyToManyField but created it in the migration as a ManyToManyField (i.e. an unsorted django.db.models.fields.related.ManyToManyField), which was inadvertently imported through sortedm2m with the following statement:

from sortedm2m.fields import ManyToManyField

The author clearly meant to use a SortedManyToManyField in the migration - since that would match the model field, and they were importing from sortedm2m - but through IDE autocomplete or simple human error, they imported the ManyToManyField.

This small change would prevent others making the same error.
