Fix django-1.6 incompatibilities

We're seeing a couple of final quirks running the testsuite on django
1.6:

  Traceback (most recent call last):

    File "/usr/lib/python2.7/dist-packages/django/db/models/fields/related.py", line 1084, in get_normalized_value
      value_list.append(getattr(value, source.attname))
  AttributeError: 'PatchChangeNotification' object has no attribute 'id'

- we're specifying our own pk here, so the PatchChangeNotification has
no id attribute; it looks like the pk__in syntax is expecting IDs.

We also need a default value for BooleanField, as we're getting
integrity errors when creating rows with no explicit send_notifications
set.
