[gnote] Fix configure failure with --disable-dbus (Closes #590560)

[Hubert Figuière <hub src gnome org>]

commit 762ed62168340e0f3afaeed196b84554a94f2b97
Author: Gilles Dartiguelongue <eva gentoo org>

    Fix configure failure with --disable-dbus (Closes #590560)
    
    AM_CONDITIONAL for HAVE_DBUS was badly placed resulting in configure
    getting confused.
