Improve passwords autocomplete

Use `autocomplete="new-password"` or `autocomplete="current-password"` to better signal to browsers and password managers how to handle the password fields.

This feature is especially useful for “change your password” and “new user” forms

   * Validations were being ignored on singup in the `Trackable#update_tracked_fields!` method. (by @AshleyFoster)
   * Do not modify options for `#serializable_hash`. (by @guigs)
   * Email confirmations were being sent on sign in/sign out for application using `mongoid` and `mongoid-paperclip` gems. This is because previously we were checking if a model is from Active Record by checking if the method `after_commit` was defined - since `mongoid` doesn' have one - but `mongoid-paperclip` gem does define one, which cause this issue.
