Title: Fix error with travis

It will fix error that caused by updating php-codesniffer.

Anyway, I thought version of the phpcs should be locked like following.

```
$ composer global require "squizlabs/php_codesniffer=1.6.5"
```

But WordPress rule will be update again in the future and it doesn't have tag.
I couldn't decide lock or not ...
