Proper handling of to_field in deconstruct for AUTH_USER_MODEL foreign key

Description

to_field shouldn't appear in the migration for a ForeignKey to settings.AUTH_USER_MODEL, otherwise the migration isn't usable if settings.AUTH_USER_MODEL uses a primary key with a name different than 'id'.

It's not necessary to include the field name, the default behavior of models.ForeignKey is to look up the primary key field name from the target model.

[1.7.x] Removed 'to_field' from ForeignKey(settings.AUTH_USER_MODEL) in admin's initial migration.

This enables using a custom user model with a primary key with a name
different than 'id'; refs #22889.
