merge: fix save_state() to work when there are stat-dirty files
When there are stat-dirty files, but no files are modified, `git stash create` exits with unsuccessful status. This causes merge to fail. Copy some code from sequencer.c's create_autostash to refresh the index first to avoid this problem. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
