Manual Checkpointing test case.
> Improve TestManualCheckpoint

> Key: GIRAPH-270

>
> A good test case for checkpointing is important as we experiment, for
> example, with storing messages separately to enable out-of-core messaging.
> There are two problems with TestManualCheckpoint:
> - It's only checking that the sum of vertex ids is invariant. This doesn't
> guarantee that we're correctly restoring vertex values, edges, and messages.
> - The "restarted job" seems to actually start from scratch, and overwrite the
> previous job's checkpoints. What we are expecting, instead, is the restarted
> job to load the latest checkpoint and start from there.
