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.
