REVISION SUMMARY
  If a folder was added to include/excludeFolders and then removed,
  there will be a stale entry in the config, for which `filePathToId`
  yields 0. When passed to `removeRecursively`, it might reinterpret it
  as tree root, which is not something we want (although there are
  checks for it inside `WriteTransaction`)
