Update index.js

On empty search, create/fetch documentos from view index by createdAt. This is bc waterline find method when is call without any query return the docs + design_views. which for restAPI is wierd. The createdAt views is bc waterline create that field for every document.

The range 1980... 2300 if bc i need that asap :P.
Update views.js

Allow to send startKey and endKey for query the view, not just a string
