    tests py_credentials: Fix encrypt_netr_crypt_password test
    
    The test uses NetrServerPasswordSet2 to change a password, this tests
    the end to end encryption.  The original call to NetrServerPasswordSet2
    was not utf-16 encoding the new password.  However the call to
    netr_DsrEnumerateDomainTrusts was using cached credentials and not
    using the new password, so this was not detected.
