Session.clear() or Session.clearAuth() results in TypeError

[dkoo]

First off, thank you for this awesome extension of Session. I'm relying on it quite a bit to hold consistent views after page refreshes and it works quite well, for the most part.

One thing I've noticed is that using Session.clear() or Session.clearAuth() (with no arguments) in my app results in a TypeError:

Exception from Tracker recompute function: meteor.js:888:11
TypeError: self._dict.keyValueDeps[akey] is undefined

In my case, I'm using it to clear Session keys when the user visits the root '/' route. This may be related to #42, but logging it here since it's a slightly different case.
