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.
