[empathy] make the presence chooser insensitive no accounts are enabled

[Sjoerd Simons <sjoerds src gnome org>]

commit 0eb14eeb66bbec5985a12c0be24bf45d00ed311c

    make the presence chooser insensitive no accounts are enabled
    
    When there are no accounts enabled, there isn't really any point in setting a
    presence and it's a bit confusing to the user as their action doesn't actually
    have a result
    
    Fixes #598354
