Broken cookies session store

[der-On]

It throws an error:

TypeError: Cannot read property 'cookies' of undefined
at Cookie.read (.../node_modules/geddy/lib/sessions/stores/cookie.js:33:29)
at init (.../node_modules/geddy/lib/sessions/index.js:103:19)
at null._onTimeout (.../node_modules/geddy/lib/sessions/index.js:67:10)
at Timer.listOnTimeout as ontimeout

Using "session" instead of "controller" in the following lines fixes it, but I'm not sure if it's correct:

https://github.com/geddy/geddy/blob/master/lib/sessions/stores/cookie.js#L33
https://github.com/geddy/geddy/blob/master/lib/sessions/stores/cookie.js#L77

The other session stores do not tackle the controller at all.
