Subject: QScopedValueRollback: make constructor explicit

I'm not even sure whether you could implicitly
convert a T& into a QScopedValueRollback<T>,
seeing as the constructor takes a non-const
reference, but it looks wrong without explicit
and

  QObject o = new QObject(parent);

also won't compile even with implicit QObject(QObject*)
under a conformant compiler because of the disabled
copy constructor, and we still make QObject(QObject*)
explicit, so add it here, too.
