Allow an annotation to match a field name when using .values on a query set.

[Andy McKay]

Ticket ​http://code.djangoproject.com/ticket/11256 has the unfortunate effect of stopping a values query from working.

class Author(models.Model):
  last_updated = models.DateField()

class Book(models.Model):
  author = models.ForeignKey(Author, related_name='books')
  pubdate = models.DateField()

authors = Author.objects.values("id").annotate(last_updated=Max('books__pubdate'))

In this case we are using values to only use that one field and last_updated is no longer overriding anything.

This is a regression in trunk, so it needs to be on the 1.3 milestone.

(In [15223]) Fixed #14707 -- Relax the protections on aggregate naming collisions when a ValuesQuerySet removes the colliding name. Thanks to Andy McKay for the report.
