rebase: catch RepoLookupError at restoring rebase state for abort/continue
Before this patch, "rebase --abort"/"--continue" may fail, when rebase
state is inconsistent: for example, the root of rebase destination
revisions recorded in rebase state file is already stripped manually.
Mercurial earlier than 2.7 allows users to do anything other than
starting new rebase, even though current rebase is not finished or
aborted yet. So, such inconsistent rebase states may be left and
forgotten in repositories.
This patch catches RepoLookupError at restoring rebase state for
abort/continue, and treat such state as "broken".
