20207	`ManyToManyField` with an unicode name fails to create an intermediary model.	Simon Charette	Simon Charette	"I encountered the following error when porting an app codebase to support both python 2 and 3.

{{{
#!python
from __future__ import unicode_literals


class Teacher(models.Model):
    students_ = models.ManyToManyField(Student, name='students')  # Here the name is a unicode string because of the future import.
}}}

Raises:

{{{
TypeError: Error when calling the metaclass bases
    type() argument 1 must be string, not unicode
}}}

The culprit is this [https://github.com/django/django/blob/8d05e6c0c7fe35df86799fa2fdcdb6499a4f6312/django/db/models/fields/related.py#L1312 line]. It should always be a `str`.

This was not introduced by the codebase port to Python 3 and thus it's not a release blocker.

Attaching a simple patch with tests in a few moments."	Bug	closed	Database layer (models, ORM)	dev	Normal	fixed			Ready for checkin	1	0	0	0	0	0
