evolve: don't embed graft data when completing interrupted evolve operations

This data shows in TortoiseHg, and is a bit awkward since it wasn't added before
in the non interrupted case.  It originated before 823031b51d81, when the
implementation changed away from using the graft command.  According to
@marmoute, unconditionally adding `source` served as noise to create a new hash
and prevent a cycle, so use the same key (`rebase_source`) as would happen in
the uninterrupted case (as demonstrated by the first change in
test-stabilize-conflict.t).

=========================================
Testing single head enforcement: Case B-5
=========================================

A repository is set to only accept a single head per name (typically named
branch). However, obsolete changesets can make this enforcement more
complicated, because they can be kept visible by other changeset on other
branch.

This case is part of a series of tests checking this behavior.

Category B: Involving obsolescence with topic
TestCase 5: Obsoleting a merge reveals two heads

.. old-state:
..
.. * 3 changesets on topic X (2 on their own branch + 1 merge)
.. * 1 changeset on topic Y (child of the merge)
..
.. new-state:
..
.. * 2 changesets on topic X (merge is obsolete) each a head
.. * 1 changeset on topic Y keeping the merge visible
..
.. expected-result:
..
.. * 2 heads detected (because we skip the merge).

Test setup
----------

  $ mkdir B5
  $ cd B5
  $ setuprepos single-head
  creating basic server and client repo
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd client
  $ hg topic -r . topic-X
  switching to topic topic-X
  changed topic on 1 changesets to "topic-X"
  $ hg strip --config extensions.strip= --hidden 'hidden()' --no-backup # clean old A0
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg topic topic-X
  marked working directory as topic: topic-X
  $ mkcommit B0
  $ hg merge
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m 'M0'
  $ hg topic topic-Y
  $ mkcommit C0
  active topic 'topic-Y' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg push --new-branch
  pushing to $TESTTMP/B5/server
  searching for changes

Actual testing
--------------

(force push to make sure we get the changeset on the remote)

  $ hg push -r 'desc("C0")' --force
  pushing to $TESTTMP/B5/server
  searching for changes
  no changes found
  transaction abort!
  rollback completed
  abort: rejecting multiple heads on branch "default//topic-X"
  (2 heads: 5a47a98cd8e5 d3826ff42cf7)
