[gnome-contacts/wip/cdavis/hdy-style-updates] contact-pane: Re-arrange widgets, subclass GtkBin

[Christopher Davis <christopherdavis src gnome org>]

commit a55c19962f96a898935f6692bb591c2f180d713d

    contact-pane: Re-arrange widgets, subclass GtkBin
    
    Subclassing GtkScrollWindow and putting the stack, etc.
    nested in the hierarchy messed with HdyStatusPage and
    caused it to have odd margins. Since HdyStatusPage also
    includes a GtkScrolledWindow, this would cause double
    scrolling as well.
    
    This commit rearranges things to work well with HdyStatusPage.
