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.

  skipping 57a3f8edf065: have a different parent than 9a1f460df8b5 (not handled yet)
  | 57a3f8edf065, 9a1f460df8b5 are not based on the same changeset.
  | With the current state of its implementation, 
  | evolve does not work in that case.
  | rebase one of them next to the other and run 
  | this command again.
  | - either: hg rebase --dest 'p1(57a3f8edf065)' -r 9a1f460df8b5
  | - or:     hg rebase --dest 'p1(9a1f460df8b5)' -r 57a3f8edf065
