JANI to Modest conversion fails for firewire.true from QComp
Using moconv to convert [the firewire.true JANI model from QComp](https://qcomp.org/benchmarks/#firewire) to a Modest model creates a property called `deadline` that collides with the integer variable `deadline` (bug), and changes the name of variable `delay` to `delay1` (feature). The result is that the toolset can work on the original JANI model, but not on the converted Modest model.
