suppress warning "QAbstractItemView::commitData called with an editor that does not belong to this view"

I added some print statements to the code to see the following:

$ bin/bornagain
DEBUG SimView::SimView immediate=0
DEBUG SimView::hideEvent
DEBUG SimView::readOptionsFromUI
SimulationOptionsItem::setRunImmediately 1 -> 0

So when the GUI is launched, the following happens:

    SimulationView is constructed, radio button m_run_policy_background_radio is constructed last, and checked by default, so m_run_policy_immediately_radio is unchecked.
    As the newly constructed SimulationView is invisible, somehow a hideEvent is triggered.
    SimView::hideEvent calls SimView::readOptionsFromUI, which overwrites the default value SimulationOptionsItem::m_run_immediately = true.

In my current understanding, the idea of tying readOptionsFromUI to hideEvent is flawed. Fortunately, it is implemented nowhere else. I will prepare a MR that simply removes SimView::hideEvent.
