Update Ecobee state after making changes to climate (#3436)

* Update Ecobee state after making changes to climate

Without this, climate and sensor state will take up to 3 minutes
(the MIN_TIME_BETWEEN_UPDATES on its update throttle) to update in
the interface, which makes it more difficult to do automation around the
state.

* Use a boolean instance variable that update can check, rather than always calling update
