sddm-theme: fix missing password field on "Other" page
On this page there is no concept of the user being passwordless because no username has been specified by the user yet; we cannot know ahead of time. As a result, userList.currentItem.needsPassword is blank so the password field gets hidden.
We should just assume that in username/password entry mode, all users have a password set. For any users where this is not the case, they can just leave the password blank, and it's not any worse than it was in Plasma 5.22.
To test, run sddm-greeter --test-mode --theme ~/kde/usr/share/sddm/themes/breeze/
(or wherever your built-from-source breeze SDDM theme lives) and go to the "Other..." page. Compare before and after applying this MR.
