graft: do not use `.remove` on a smart set (regression)

Revset calls use to return a list. Graft use to mutate that list. We cannot do
this anymore leading to a crash when grafting multiple changeset with a revset.

    File ".../mercurial/commands.py", line 3117, in graft
      revs.remove(rev)
    AttributeError: '_addset' object has no attribute 'remove'

We are late in code-freeze so we make the shortest possible fix by turning it
back to a list.

  $ hg init

  $ touch to-be-deleted
  $ hg add
  adding to-be-deleted
  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path

  $ hg up -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
