Default state store does not get instantiated on flows.statestore in Django 1.6

[sergioisidoro]

 def setup():
      self = sys.modules[__name__]
     self.state_store = _get_state_store()

Fails to instantiate state_store in some cases, resulting in failure in a clean installation on 2.7, Django 1.6.

with the simple code:

from flows.handler import FlowHandler
