Add 1.8 alpha support

[tomchristie]

Add 1.8 alpha to the test matrix and resolve any issues.

The current builds against Django master indicate that there are some failures that will need resolving. It's unclear what's causing these. If they're not due to us using private Django API and they're not documented changes then it could also be valid to raise any upgrade issues 1.8 alpha presents as Django tickets.

Is there a PR already for this ?

[tomchristie]

Nope nothing yet.

I checked this out a few weeks ago: the majority of the failures against Django master (Failed: Database access not allowed, use the "django_db" mark to enable) have to do with pytest-django's compatibility with Django 1.8.

@pelme recently merged in support for 1.8, but has not released the updates on PyPI yet.

@DavidMuller A new version is released now, so it should now be fixed :)

[tomchristie]

Closed thanks to work by @DavidMuller in #2427.

Thanks again!

Reopening this - hadn't noticed that 1.8-alpha is currently in the "expected failure" column.
Evidently still work to do here.

Django-filter are working on an update for 1.8 support:
carltongibson/django-filter#210

Some issues due to this change in Django behavior which I've raised as an issue... https://code.djangoproject.com/ticket/24208#ticket

[tomchristie]

Resolved by #2446.
django-filter is currently not included in our test matrix for 1.8 so we don't yet have support there, but we can add that once they've resolved any issues there.
