unpack-trees: do not fail reset because of unmerged skipped entry

After modify/delete merge conflict happens in a file skipped by sparse
checkout, "git reset --merge", which implements the "--abort" actions,
and "git reset --hard" fail with message "Entry * not uptodate. Cannot
update sparse checkout."

As explained in [1], the up-to-date checker mistakenly treats conflicted
entry which does not exist in HEAD as still skipped by sparse checkout.

Use the fix suggested in [1]. Also, add test case which verifies the
issue is fixed.
