Fix parsing bug which causes range(variable) to crash the engine 

problem was a segmentation fault caused by trying to access Vector constants[0] which isn't there if op->arguments.size() is not bigger than one.

- the changed OR condition didn't make sense (always true), should be AND
- changes the "constant" variable to be false per default and gets set to true when there is actually something pushed to "constants"
