rebase: always pass destination as revnum to _handleskippingobsolete()
We were passing it as a revision number in one place and as a context
in another. It worked because the only use was in "repo[dest].rev()",
but it was confusing. By always passing a revision number, we can also
remove that unnecessary lookup.
