prev: fix the breakage of `hg previous` from obsolete cset

This patch fix the breakage of `hg prev` from obsolete changeset when topic is
involved. We get the topicidx of it's succesor and proceed.

Check we can find the topic extensions

  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  $ mkcommit() {
  >    echo "$1" > "$1"
  >    hg add "$1"
  >    hg ci -m "add $1"
  > }

Create a simple setup

  $ hg init repoa
  $ cd repoa
  $ mkcommit aaa
  $ mkcommit bbb
  $ hg topic foo
  marked working directory as topic: foo
  $ mkcommit ccc
  active topic 'foo' grew its first changeset
  $ mkcommit ddd
  $ mkcommit eee
  $ mkcommit fff
  $ hg topic bar
  $ mkcommit ggg
  active topic 'bar' grew its first changeset
  $ mkcommit hhh
  $ mkcommit iii
  $ mkcommit jjj

  $ hg log -G

Tests next and prev behavior
============================

Basic move are restricted to the current topic

  $ hg up foo
  switching to topic foo
  0 files updated, 0 files merged, 4 files removed, 0 files unresolved
  $ hg prev
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  [12] add eee
  $ hg next
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [13] add fff
  $ hg next
  no children on topic "foo"
  do you want --no-topic
  [1]
  $ hg next --no-topic
  switching to topic bar
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  [14] add ggg
  $ hg prev
  preserving the current topic 'bar'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  [13] add fff
  $ hg prev
  no parent in topic "bar"
  (do you want --no-topic)
  [1]
  $ hg prev --no-topic
  switching to topic foo
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  [12] add eee

When the current topic, obsoleted changesets topic and successor topic are same

  $ hg up 20bc4d02aa62

  $ echo foobar >> hhh
  $ hg amend
  $ hg up 20bc4d02aa62
