Attempt to parse misconfigured license declaration

[gantoine]

Running delice on a project kept failing to parse the emojione package.json licenses declaration, since it's misconfigured as an object, and not an array.

"licenses": {
  "type": "(MIT)",
  "url": "https://github.com/emojione/emojione/blob/master/LICENSE.md"
},

This PR attempts to address missing and misconfigured licenses declarations by handling objects. I considered ignoring it and simply return "invalid license", but since this was the only case, it felt better to address it "correctly".

I tested this and it also fixes cutenode/delice#2

Their issue was coming from the same type of error, a licenses field which was an object
