rebase: fix crash when rebase aborts while rebasing obsolete revisions

Before this patch, rebase --continue would crash when trying to resume a rebase
of obsolete revisions whose successors were in the destination.
This patch adds logic to recompute the mapping when rebase is resumed. This
patch also adds a test that showcased the crash before the code change.

rebase --continue + skipped rev because their successors are in destination
we make a change in trunk and work on conflicting changes to make rebase abort.

  $ hg log -G -r 17::
  @  17:61bd55f69bc4 bar foo

  ~

Create the two changes in trunk
  $ printf "a" > willconflict
  $ hg add willconflict
  $ hg commit -m "willconflict first version"

  $ printf "dummy" > C
  $ hg commit -m "dummy change successor"

Create the changes that we will rebase
  $ hg update -C 17 -q
  $ printf "b" > willconflict
  $ hg add willconflict
  $ hg commit -m "willconflict second version"
  created new head
  $ printf "dummy" > K
  $ hg add K
  $ hg commit -m "dummy change"
  $ printf "dummy" > L
  $ hg add L
  $ hg commit -m "dummy change"
