`parseLinks` shouldn't update state

[wyuenho]

As discovered in #136 and #139, a state shouldn't be sent down from the server. The totalRecords and related states will be calculated when the new records are added to the fullCollection after fetch, thus totalRecords must and should always be equal to fullCollection.length under infinite mode. If parseLinks tries to be too smart, the state has already been updated in parseLinks, the subsequent fullCollection.add operation after fetching has the potential to give the wrong result. The behavior is too surprising.
