Cannot rename model keeping db table name

[rhcarvalho]

Django migrations do not work when you rename a model keeping the db table name. For instance:

# -- models.py --
class Book(models.Model):

name = models.CharField()
class Meta:

db_table = "books"

# -- models.py after renaming model --
class AwesomeBook(models.Model):

name = models.CharField()
class Meta:

db_table = "books"

The migration system ends up making an operational error by trying to rename the table from books to books, when the rename is unnecessary.
