Description
When a model gains a UniqueConstraint, makemigrations doesn't check that the fields named therein actually exist.
This is in contrast to the older unique_together syntax, which raises models.E012 if the fields don't exist.
In the attached demonstration, you'll need to uncomment "with_unique_together" in settings.py in order to show that unique_together raises E102.
