Handle 'non-ASCII in password' warning for Russian installs
    
    Summary:
    Since 26.17, anaconda shows a warning when the user password
    contains non-ASCII characters, and requires a second Done click
    to confirm. This change should handle that.
    
    On the 'catch cases where password typing went wrong and re-try'
    bit: to keep that, but not re-type the password *every single
    time* on the Russian install test, we'd have to make the needle
    match the text of the warning. This is problematic because then
    that needle will be able to break without us easily noticing;
    that's why I wanted to keep the 'warning bar' needle text-free.
    Unfortunately, that means we have to skip the protection for
    switched-layout installs.
    
    Note the protection was actually not working for any non-English
    install anyhow, because the needle had `LANGUAGE-english` as a
    tag. We never noticed that. Failed password typing is pretty
    rare now, so we can live without the protection - it's just nice
    to have it for the English install tests because there's so many
    of them.
    
    Test Plan:
    Run the Russian install with a recent Rawhide image,
    check it clicks 'Done' twice. Note, it will still fail, because
    of RHBZ #1413813.
