DiffFormatterTest: Add a test to confirm the default rename detection settings

Add a test that confirms:

- No rename detector is initialized by default

- Rename detector is initialized after calling setDetectRenames(true)

- Rename limit and rename score have the default values 400 and
  60, respectively. Note that there are no constants for these values
  so the test hard codes them.
