[issue45970] Py_NewInterpreter causes bogus fatal error along the failure path

[Jason Haslam]

New submission from Jason Haslam <jason.haslam at gmail.com>:

The failure cleanup of `Py_NewInterpreter` causes a bogus fatal error on the call to `PyThreadState_Delete`. The error is about deleting the current thread state. The saved thread state should be swapped back in *before* deleting the new thread state.
