Mocks of ListType ignore field 'choices' parameter

ListField ignores choices parameter of underlying field when creating mock object. Here is minimal code that reproduces error:

from schematics.types import StringType, ListType
from schematics.models import Model


class Foo(Model):
    bar = StringType(choices=["lol", "kek"], required=True)
    baz = ListType(StringType(choices=["lol", "kek"]), required=True)


print(Foo.get_mock_object().to_primitive())
# >> {'bar': 'kek', 'baz': ['mwhot1h', '57kMabXP', 'koMg', 'GBtlbJQvT', '']}

It seems to work fine with params like max_length though, so i don't know what the deal is. Have i just missed something that's specified in docs?

With current behavior, objects generated by mocking fail to validate against model, which is frustrating.
