The password validation error should not show the password score

I have fixed this issue and providing a patch, please review.

The password validation error currently shows the password score, which is not a good user experience.

This claim is debatable. Without any kind of supporting evidence, or general agreement of those using the module, I'm inclined to say I won't change this.

I would also argue the opposite: providing some indication of the bar that must be met to have a strong-enough password is helpful, even if imperfect.
