pg-cursor no longer returns the empty array 'done' signal to the callback until the cursor recieves a readyForQuery message. This means pg-query-stream will not emit 'close' or 'end' events until the server is __truly__ ready for the next query. This fixes some race-conditions where some queries are triggered off of the `end` event of the query-stream closes #3
