Summary: Previously `_getrevstobackup()` would load manifest for each commit in memory only to check if a file was deleted in this commit or not. Manifest can be quite big and since every loaded flatmanifest is cached in fastmanifest then memory usage can be huge. Since we are doing this only to check if there are any commits that were downloaded to the client without filelogs and then were stripped server-side. This cases are rare and it would be easier to track these commits in the config file.
