Fix fullfarm layout optimization and remove accidental hotfix inclusion

remove the hotfix that made it to develop:
https://github.com/WISDEM/Ard/blob/f7fa11d489bbfec3acd63596e64e4c7b90c15943/ard/api/interface.py#L270

if commented out, an optimization with full (x,y) optimization will fail due to some input default funkiness I couldn't figure out.
