apply: test that we can't rename a file after modifying it Multiple deltas can exist in a diff, and can be applied in-order. However if there exists a delta that renames a file, it must be first, so that other deltas can reference the resulting target file. git enforces this (`error: already exists in index`), so ensure that we do, too.
