GUI: crash at specular calculation with data

Problem appeared after MR971

1. Create Instrument, sample, add data, link data to instrument.
2. Run simulation with data --> crash:

"terminate called after throwing an instance of 'Error'

what(): Error in DataPropertyContainer::addItem: hosting models are different

Aborted (core dumped)"

Simulation with 2D data works.
