Subject: Remove GetTotalBlocksEstimate and checkpoint tests that test nothing.

GetTotalBlocksEstimate is no longer used and it was the only thing
 the checkpoint tests were testing.

Since checkpoints are on their way out it makes more sense to remove
 the test file than to cook up a new pointless test.
