fix(renameSync): Resolve gitemplate issue

- (Issue: Descendant files of source dir did not exist after rename.)
- Reuse renameSync() in copyTree.
- Remove 'sandbox', 'fsStub' settings from FileStub instances
- Stop re-make()'ing stubs after updating their readdir config. Instead,
  readdir() now accepts an array of path strings and responsible for
  updating the stub returns(), rather than in make().
