rebase: adds storing collapse message (issue4792)

Before this patch collapse message wasn't stored so when
you ran into the merge conflict while rebasing, running
rebase --continue didn't remember the message and
always opened editor to fill commit message.

This patch adds saving collapse message in
.hg/last-message.txt and restoring it later
when needed.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
