Fix checkout bug rmv untracked trees from index

Browse Source 
When checking out with the GIT_CHECKOUT_REMOVE_UNTRACKED option
and there was an entire tree in the working directory and in the
index that is not in the baseline nor target commit, the tree was
correctly(?) removed from the working directory but was not
successfully removed from the index.  This fixes that and adds a
test of the functionality.
