evolve: delete redundant and incorrect code for updating dirstate

In relocate() when we notice conflicts, we will try to fix up the
dirstate by calling copies.duplicatecopies() and
dirstatedance(). However, we had called _evolvemerge() just before
that point and that has already fixed up the dirstate, so there's no
need to do it again. Also, we did it incorrectly as the test case
shows.

hg evolve --continue and obsmarkers after conflict resolution with no changes to commit (issue5967)

  $ . $TESTDIR/testlib/common.sh

  $ hg init issue5967
  $ cd issue5967
  $ cat > .hg/hgrc << EOF
  > [alias]
  > glog = log -GT "{rev}: {desc}"

  $ echo apple > a
  $ hg ci -qAm 'apple'
  $ echo banana > a
  $ hg ci -m 'banana'

Amending revision 0 in a way that causes conflicts

  $ hg prev
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [0] apple
  $ echo apricot > a
  $ hg amend -m 'apricot'
  1 new orphan changesets

  $ hg glog
  @  2: apricot
  
  *  1: banana
  |
  x  0: apple
  

Trying to evolve, then manually discarding changes from revision 1

  $ hg evolve
  move:[1] banana
  atop:[2] apricot
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  unresolved merge conflicts
  (see 'hg help evolve.interrupted')
  [1]

  $ echo apricot > a
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg evolve --continue

This will correctly notice that revision 1 can be dropped

  $ hg evolve --continue
  evolving 1:dd9b5dd30cd6 "banana"
  evolution of 1:dd9b5dd30cd6 created no changes to commit
  working directory is now at 4d6fec23dcc4
  $ hg glog
  @  2: apricot
  

This is important: 1 should not have a successor (especially not revision 2)

  $ hg olog --all
  @  4d6fec23dcc4 (2) apricot
