Change invalid password reset form language

Change invalid password reset form language

The old workflow was login -> go to a password change form (at which
point the user is fully logged on and can just abandon the form).
The AuthManager workflow is go through a string of login providers
(including the password reset), and get logged in at the very end
- so the user has to submit the form. The submit button text for not
updating the password was changed from Cancel to Skip to account for
that; this patch updates the messages which reference that text.
