shelve: find shelvedctx from bundle even if they are already in the repo
We use the new "duplicates" node tracking to find the tip of the bundle even if
it already exists in the repository.
Such logic is not supposed to be needed in theory. If the shelve was made using
internal-phase, we already know its node. Otherwise, the bundle content should
have been stripped. However, handling it makes the shelve code more robust and
provide a good example of "revduplicates" usage.
