[PATCH 3/8] apply: fix adding new files on i-t-a entries

From

Applying a patch that adds a file when that file is registered with "git add -N" will fail with message "already exists in index" because git-apply checks, sees those i-t-a entries and aborts. git-apply does not realize those are for bookkeeping only, they do not really exist in the index. This patch tightens the "exists in index" check, ignoring i-t-a entries.
