Revert old changes and apply new strategy to add pagination support.

@eddyystop as you alluded to on slack, I feel this is a better solution for adding pagination support. Disable pagination by default for service calls from the loaderFactory.

I agree this is a better solution. It causes the default behavior to return correct results.

One reason, often the main reason, for using pagination is to reduce the load on the database from any one service call. The maximum load imposed by the batchloader can be controlled by its maxBatchSize option.
