[push][validate][info] commands don't work with path to datapackage.json

[anuveyatsu]

If I run data push datapackage.json, data validate datapackage.json or data info datapackage.json (on any OS) it fails saying:

> Error! ENOTDIR: not a directory, stat '/.../.../.../datapackage.json/my-file.csv'

How to reproduce

• create a project for dataset and have datapackage.json in cwd
• run data push datapackage.json
• run data validate datapackage.json
• run data info datapackage.json
• see the error

Expected behavior

• should just work - push or validate
