Title: Better v1_key not found error, plus miq_ae_password_spec

Customer ran into errors with miq ae password.
Turned out to be user error, but wanted to added specs in areas that we were digging.

Modified error message when a legacy key (e.g.: `v1_key`) is not present. (false doesn't have decrypt64 is a little cryptic)
