-v should pass -V to knife... or something

[jaymzh]

When taste-tester upload calls knife and knife finds a syntax error on a file in a cookbook it doesn't tell you what cookbook or what file. To debug you have to take the knife command from the output and then run it with -VV which is a bit cumbersome.

I'll probably send a PR for this, I'm just making the Issue so I don't forget.

Knife is called from the between-meals, so, the between meals should be changed, not taste-tester. Here is a pull request: facebook/between-meals#104
