[orca] More on adjust when we clear the active window and focus in event manager

[Joanmarie Diggs <joanied src gnome org>]

commit 014b369fc5aab67cb764bdc246ee7550cb1bc8a5

    More on adjust when we clear the active window and focus in event manager
    
    Also apply the previous change when we cannot even check if the event
    source is defunct because the window is already truly dead and checking
    triggers an exception.
