split: preserve phase of commit that is being split

With this change, hg split will preserve the phase of the commit that is being
split, ignoring the phases.new-commit setting. Previously, we would use whatever
phases.new-commit was set to (unless our parent was secret, then we would be
secret even if phases.new-commit=draft).

Now, splitting a draft commit with phases.new-commit=secret does not cause the
new commits to become secret, and splitting a secret commit with
phases.new-commit=draft and a draft parent does not cause the new commits to
become draft.

Test cases and commit message taken from Kyle Lippincott's D2016 (thanks!).

Preserve secret phase in split

  $ cp -R $TESTTMP/clean $TESTTMP/phases1
  $ cd $TESTTMP/phases1
  $ hg phase --secret -fr tip
  $ hg log -T '{short(node)} {phase}\n'
  1df0d5c5a3ab secret
  a61bcde8c529 draft
  $ runsplit tip >/dev/null
  $ hg log -T '{short(node)} {phase}\n'
  00eebaf8d2e2 secret
  a09ad58faae3 secret
  e704349bd21b secret

Do not move things to secret even if phases.new-commit=secret

  $ cp -R $TESTTMP/clean $TESTTMP/phases2
  $ cd $TESTTMP/phases2
  $ cat >> .hg/hgrc <<EOF
  > [phases]
  > new-commit=secret
  > EOF
  $ hg log -T '{short(node)} {phase}\n'
  1df0d5c5a3ab draft

  $ runsplit tip >/dev/null
  $ hg log -T '{short(node)} {phase}\n'
