    SignonAuthProvider: fix ref counting issue

    The account data was unreferenced once too often, or rather, a suitable ref
    count increase was missing. A debug build of glib detects that ("GLib:
    g_variant_unref: assertion 'value->ref_count > 0' failed"), but without
that
    check the code might also crash.
