SSLSocket.get_verified_chain() and get_unverified_chain() accessed
self._sslobj without the _checkClosed() / None guard used by every other
query method, so they raised AttributeError when called after the TLS layer
was torn down (for example after unwrap()). Add the guard and return an empty
list, matching the value these methods return for an empty chain.
