Clean up isPending because it was being used before by ckptInitialConsume but that routine is disabled (doesn't do anything) or not needed anymore because of master syncup.

fix issue #45 #39 #14 update
Fix build break from Cang's commit f856842 for Issue #20 that removed unused isPending flag in ckpt. Hopefully, a simple build in future before a commit would avoid such build breaks and c3po-z1 test stalls. Closes #20
