Double change detection with files promise and changes body using "best" hashing

A user emailed me directly:

I have changed the hashing to "md5" from "best" and that has done away with the double change detection.
As far as reproducing, you should be able to make a change detection file promise on a directory using "best" hashing and observe that changes are detected twice on subsequent runs of the agent. Changing to md5 hashing fixes the issue for me, btw I am using "content" only for changes detection.
