Monty Taylor 635be2a3ae Fix cleanup of symlink fixtures
These aren't all getting cleaned up, which winds up breaking
the second runs. Instead of doing addCleanup with a method that
does the loop again, which can fail in the middle and not
clean up subsequent files, add an individual cleanup when we
add the symlink. This results in all of the symlinks consistently
being cleaned.
