Tests failed on non-English Windows.

[asakaxgit]

Most of tests failed due to mis-detection of locale.
Many tests of FilterTest are strongly relied on Language of occuring messages.
Expected messages in expected.txt are written in English.
So we need to fix tests to fixed locale as English, or respect running machine's language.
