Investigate calling get_state(True) from the Device base class constructor.

[esev]

Possible enhancement idea: The Bridge, CoffeeMaker, CrockPot, Humidifier, Insight, and Maker devices all call the equivalent of self.get_state(force_update=False) inside __init__. If that logic was moved into the Device base class, so it'd apply to all device classes, I think that would have avoided the bug from #633.
