rebase: fix regression in file change detection introduced by 0ecb3b11fcad

Before 0ecb3b11fcad, `wctx._compact()`, was called by `wctx.nofilechanges()` as
a side effect. Later, it turned out that this side effect is needed to correctly
detect which files changed. See https://phab.mercurial-scm.org/D8733#131949 for
the history.

The problem could also be triggered by running `tests/test-rebase-parameters.t`
with `--extra-config-opt rebase.experimental.inmemory=1`.

====================================
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 branch default
.. * 1-changeset on branch Z (between the two other)
..
.. new-state:
..
.. * 2-changeset on branch default, on untouched, the other moved
.. * 1-changeset on branch 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 branch Z
  marked working directory as branch Z
  (branches are permanent and global, did you want a bookmark?)
  $ mkcommit B0
  $ hg branch default --force
  marked working directory as branch default
  $ mkcommit C0
  created new head
  $ hg push --new-branch
  pushing to $TESTTMP/E1/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 2 changesets with 2 changes to 2 files
  $ hg up 0
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ mkcommit C1
  created new head
  $ 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 dc44c53142f0!
  (merge or see 'hg help push' for details about pushing new heads)
