Do not autocomplete the user password for express installations

Description
After installing the same system for the second time I've noticed that the password was pre-filled by the time I reached the express-installation wizard.
Some user who's not paying that much attention my just click "Continue" and end up with a VM installed that they cannot log in to (as they don't know which was the pre-filled password).
