Avoid Python memory leaks in hstore_plpython and jsonb_plpython.

Fix some places where we might fail to do Py_DECREF() on a Python
object (thereby leaking it for the rest of the session).  Almost
all of the risks were in error-recovery paths, which we don't really
expect to hit anyway.  Hence, while this is definitely a bug fix,
it doesn't quite seem worth back-patching.
