The cctests were wrong, since they access the first parameter using `Parameter(0)`. They should instead use `Parameter(1)`, since the index 0 is the receiver, and the receiver is set to be always the undefined object in `FunctionTester::Call`.

The reason it used to work is that the tests would set up an access to the stack with the wrong number of parameters, accessing only a stack suffix.
