Add IME automated tests

[luixxiul]

Describe the issue you encountered: Per #9031 (review)

It would be interesting to think about (in the future) a way to have an integration test that uses IME... for autofill or typing in the URL bar. We couldn't include it as part of the standard tests since not everybody has their system/locale setup in a way that enables IME, but we could have a dedicated machine for setting the locale / running the tests

• Any related issues:

To enable IME (Japanese) on Debian, there's an IME which looks like Google IME, called ibus-mozc.

apt-get install ibus-mozc should install the Japanese IME on your linux. I'm wondering if this could be integrated with travis.

thanks for capturing this, @luixxiul 😄

We have a private Jenkins instance which has Ubuntu 14 which we have full control over. I can install / configure it for Japanese if you had some steps. Enabling the input method editor is usually easy, but I'm curious about other concerns too (setting locale / region on top of language... recommended default settings for Japanese, etc...).

Later I'll install Ubuntu (en-US) afresh and log the steps to enable IME :-)
