"test extras / build (juman)" failed. Umm...

Thanks for contributing!
Please add the followings as test cases in test_knp_dependency_parser

解析格:ガ２ 「象は鼻が長い」
係:ト格 with 並列タイプ 「リンゴとナシとミカン」
数詞 of 名詞 「三匹の子ぶた」
接頭辞 「御盃を相交わす」

I've found that JUMAN++ mistakes ナシ for 形容詞, but not JUMAN. Well, I'll change the example to バナナ for the test.

I've also found that JUMAN cuts 子ぶた into 子 and ぶた, but not JUMAN++. Umm, I'll change it for 三匹の豚.

Please merge origin/master into this branch for the test.

I've written about this commit for conj in my diary.

Cool! Thank you very much!
