skip moving cold blocks when running with a noop coldstore

it is a noop but it still takes (a lot of) time because it has to read all the cold blocks.

treat Has as an implicit Write
...
Rationale: the VM uses the Has check to avoid issuing a duplicate Write in the blockstore.
This means that live objects that would be otherwise written are not actually written, resulting
in the first write epoch being considered the write epoch.

after the mark completes and during the purge; if this happens we will purge
