Always copy SignalIconState when keeping a reference

Defensively copy SignalIconState so that StatusBarWifiView and
StatusBarMobileView can properly detect changes to state.

Also don't do visibility changes if setting the same visibleState on
StatusBarWifiView.

Test: turn wifi on and off; verify that it goes away properly in status
bar
