uic creates ambiguous signal/slot connections

Invalid connections were generated from this ui https://github.com/psi-im/psi/blob/32ce4042ee52a48807367f696fa5fe2b919c3716/src/options/opt_appearance_misc.ui

QObject::connect(sl_rosterop, &QSlider::valueChanged, lb_rosterop_val, &QLabel::setNum);
QObject::connect(sl_chatdlgop, &QSlider::valueChanged, lb_chatdlgop_val, &QLabel::setNum); 

There are two QLabel::setNum methods which can accept int and double, but the generated code doesn't have qOverload.

This issue is very similar to https://bugreports.qt.io/browse/QTBUG-90308
