split: demonstrate that discard after more than one commit is misbehaving

The `assert` that this patch removes was introduced in 9242d0b5f74d, when we
didn't have the test that this patch adds. Without the `assert` we can actually
see the incorrect behavior. With it, the test would throw an AssertionError
just before "forgetting c", when hg split is handling the second discard
action.

====================================
Testing head checking code: Case E-3
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

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

Category E: case involving changeset on multiple branch
TestCase 8: moving only part of the interleaved branch away, creating 2 heads

.. old-state:
..
.. * 2-changeset on topic Y
.. * 1-changeset on topic Z (between the two other)
..
.. new-state:
..
.. * 2-changeset on topic Y, on untouched, the other moved
.. * 1-changeset on topic Z (at the same location)
..
.. expected-result:
..
.. * push rejected

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

  $ mkdir E1
  $ cd E1
  $ setuprepos
  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 . Y
  switching to topic Y
  changed topic on 1 changesets to "Y"
  $ hg strip --config extensions.strip= --hidden 'hidden()' # clean old A0
  saved backup bundle to $TESTTMP/E1/client/.hg/strip-backup/8aaa48160adc-19166392-backup.hg
  $ hg topic Z
  $ mkcommit B0
  active topic 'Z' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg topic Y
  $ mkcommit C0
  $ hg push
  pushing to $TESTTMP/E1/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 3 changesets with 2 changes to 3 files (+1 heads)
  1 new obsolescence markers
  obsoleted 1 changesets
  $ hg up 0
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg topic Y
  marked working directory as topic: Y
  $ mkcommit C1
  $ hg debugobsolete `getid "desc(C0)" ` `getid "desc(C1)"`
  1 new obsolescence markers
  obsoleted 1 changesets
  $ hg log -G --hidden

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

  $ hg push -r 'desc("C1")'
  pushing to $TESTTMP/E1/server
  searching for changes
  abort: push creates new remote head 57530ca5eb24 on branch 'default:Y'!
  (merge or see 'hg help push' for details about pushing new heads)
