rust-status: save new dircache even if just invalidated

There was a functional race between invalidating the cache (not acted upon
until the end of the status algorithm) and populating the new cache (which
relies upon an up-to-date version of the cache).

We simply inform the cache populating function that we've just invalidated
the cache for this particular directory since the information is present in
the same scope.
