Make %w and %# work for bell notifications

Since commit c3982cfb, bell notifications include the display title, in
addition to the name title, to help identifying which tab the
notification came from.  Unfortunately, %w (which can be quite useful in
identifying tabs) and %# weren't working for this case, neither for the
DBUS query:

qdbus $KONSOLE_DBUS_SERVICE $KONSOLE_DBUS_SESSION org.kde.konsole.Session.title 1
