bodyBlacklist fails when blacklist property is the only one in body and requestWhitelist has body.

[ghost]

Example:

• Set bodyBlacklist: ['foo']
• Set requestWhitelist: ['body']
• Send a request with a body where the only property is foo i.e { foo: 'foobar' }
• express-winston will still log out { foo: 'foobar' } as the body.
• Adding another property to the body will cause it to be stripped out correctly i.e. { foo: 'thisWillNotPrint', someProp: 'thisWillPrint' }

This appears to be the underlying culprit: https://github.com/bithavoc/express-winston/blob/master/index.js#L246-L247

Will see if I can get a PR up soon to resolve.
