Summary:
Include some basic testing of Japanese input, and split the
input testing (including Russian) into a separate module, since
it's not really part of 'login' testing.
Test Plan:
Run the test, and the Russian and French tests too to
make sure they didn't break. Tested on staging. Note the Japanese
test soft fails, intentionally, at present, as I discovered a bug
while working on it:
