InterSimPhoNyFoam missing

[ahashibon]

In foam_internalwrapper/foam_dicts.py, interFOAM solver is mapped to the non-existent interSimPhoNzFoam, need to remove it to get it running, as we use the vanilla solver here.

def get_simphony_io_solver(foam_solver):
simphony_solvers = {'pimpleFoam': 'pimpleSimphonyFoam',
'simpleFoam': 'simpleSimphonyFoam',
'interFoam': 'interFoam',
'driftFluxFoam': 'driftFluxSimphonyFoam'}
return simphony_solvers[foam_solver]
