BlameGenerator: Annotate #getRenameDetector as Nullable 

The renameDetector member returned by this method will be null when
following file renames has been disabled by previously calling:

  setFollowFileRenames(false).

Annotate it as @Nullable and update the Javadoc to explicitly
document the null return.
