vm: immediately release arguments on calls with invalid spreads

Ensure to release the `this` context and the temporary argument stash
when we raise a non iterable type exception due to non-iterable values
while precessing spread operations in function call arguments.

Those values would've been garbage collected eventually but explicitly
releasing them here will allow the vm to free them immediately.
