Don't short-circuit setting StatusBarState if the upcoming state differs.

This signals that a status bar state transition has been interrupted,
and we're re-setting the status bar state before the upcoming state
could be applied. This means that some components (such as the shade)
could be partially showing the upcoming state still. In these cases, we
should proactively re-apply the current state.
