Fixed AutoScale timer not stopping #36
Fixed AutoScale timer not stopping #36

The PushServiceBase uses a timer to check the scale (if autoscaling is
enabled).  This timer was not being stopped once the service itself was
stopped and could cause exceptions to be thrown if the timer fired after
a service was stopped.
