32676	Migration autodetector changes related_name for self-referential ManyToManyField.	Mariusz Felisiak	David Wobrock	"Migration autodetector no longer adds a model name to the `related_name` attribute for self-referential `ManyToManyField`, e.g. for a field
{{{
class MyModel2(models.Model):
    field_3 = models.ManyToManyField('self')
}}}
it creates a migration with `related_name='field_3_rel_+'` instead of `related_name='_mymodel2_field_3_+'`.
