This fix corrects a problem where ChaCha20-Poly1305 objects prior to init throw NPE when getParameters() is called. It will now generate parameters containing a random nonce on each pre-init call to getParameters(). Post-initialization calls to the getParameters() method will always return the same set of parameters until the next initialization occurs.
