done:
I have now properly renamed the aliases for the test key.
Since there is no new key material in this update, there is no need to reinstall the keystore. The update is only useful for developers to locate which "standard" key they should use.
Sorry for the trouble and thanks for pointing the problem.
P.S. I hate the keystore... with a passion. Hopefully all is well now, but let me know if I goof again.
