Avoid "diff-index --cached" optimization under --find-copies-harder
When find-copies-harder is in effect, the diff frontends are expected to
feed all paths, not just changed paths, to the diffcore, so that copy
sources can be picked up. In such a case, not descending into subtrees
using the cache-tree information is simply wrong.
