convert_django_field_with_choices appears not to work

[crucialfelix]

Hi. Given:

RATING_CHOICES = (
    (0, ''),   # or (0 'none')
    (1, '*'), 
    (2, '**'),
    (3, '***'), 
    (4, '****'), 
    (5, '*****')
)

class Note(models.Model):

    rating = models.IntegerField(choices=RATING_CHOICES, blank=True, default=0)

# ...
class NoteNode(DjangoObjectType):

    class Meta:
        model = Note
        interfaces = (relay.Node,)

# fails when loading the schema
from mattermind.schema import schema

I get a failure to auto-create:

choices [(0, 0, ''), (1, 1, '*'), (2, 2, '**'), (3, 3, '***'), (4, 4, '****'), (5, 5, '*****')]
named_choices [(0, 0), (1, 1), (2, 2), (3, 3), (4, 4), (5, 5)]
named_choices_descriptions {0: '', 1: '*', 2: '**', 3: '***', 4: '****', 5: '*****'}

named_choices looks wrong.

Awesome project, everything else has been very simple so far, thanks !

I'm not sure if this is the same issue or just related to the same area, but I'm getting the choice labels coming back at the values. e.g.

PAYROLL_CYCLE_CHOICES = (
        ("weekly", "Every week"),
        ("fortnightly", "Every second week"),
        ("monthly", "Once a month")
    )

when queried comes back as:

EVERY_SECOND_WEEK

This should be fixed by #23.
(The choice labels are not longer the description values)

Fixed in master/v1.1.0.
