Damien George 0c9d452370 py/vm: Fix case of throwing GeneratorExit type into yield-from.
mp_make_raise_obj must be used to convert a possible exception type to an
instance object, otherwise the VM may raise a non-exception object.

An existing test is adjusted to test this case, with the original test
already moved to generator_throw.py.
