roll `test/api_mocha.ls` back to old end_of_line

@kong0107 seemed to change the new line character while editting
`test/api_mocha.ls` in WinXP. This commits the same file after
installing [EditorConfig Notepad++
Plugin](https://github.com/editorconfig/editorconfig-notepad-plus-plus#readme)
and re-save it.
