Always update tray icon on state change

The tray icon and its tip text get updated to the connecting state when starting
a new status window thread. This is not enough for persistent connections as these
can be restarted from the hold state which does not go through a new thread creation.

To see the bug, disconnect and reconnect a persistent connection and have it wait in the
connecting state. The tray icon colour does not change to yellow and the tray tip message
does not show the "Connecting to:" text.

Fix by ensuring that  CheckAndSetTrayIcon() or SetTrayIcon() gets called whenever a state
change message is received.

Fixes issue #668
