Avoid warnings on null actors for tray icons

Browse Source 
Plugging the GtkSocket icon can fail, in which case NaTrayManager emits
tray-icon-removed but the icon has never emitted plug-added, thus the
ShellTrayIcon has not been created. This results in various criticals
and exceptions in the tray-icon-removed handler.
