Currently `RepoTree.open` will throw FileNotFoundError if you have a file that is tracked by dvc, but which has no md5 or a cache for which is missing, even though you have the file itself in your workspace. This corresponds very nicely to the `--no-commit` or `--no-exec` scenario, where you might not want to commit your artifacts to cache just yet. Fixes #3974
