rebase: catch RepoLookupError at restoring rebase state for summary

Before this patch, "hg summary" may fail, when there is inconsistent
rebase state: 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
summary hook, and treat such state as "broken".
