    entry: Handle no-window events in gtk_entry_event
    
    gtk_entry_event's goal is to detect if a specific event concerns one of the two
    entry icons. It can happen that this function is called during initialization
    and/or before the entry is realized. In this case the entry icons (and the
    event) will not yet have an associated window. The code should consider the
    aforementioned situation and avoid matching a icon and an event with no
    associated windows.
