[BUG] Infinite loop when performing operations on parameters

[Aayan]

Performing operations on function parameters causes the program to get stuck within an infinite loop

Steps to reproduce the behavior:

1. Launch birb shell with the birb command
2. Type

void addAndPrint(int a, int b) {
   screm(a+b);
}

addAndPrint(5, 7);

3. Run program with runBirb() command
4. See error

The program should be printing 12

Starts the loop within visitFuncCall (runtime.dart)
