phases: use revision number in analyze_remote_phases
Same logic as the previous change to `new_heads`, see rationnal there.
This avoids a small number of `nodes -> revs` conversion speeding thing up in
the 100 milliseconds order of magnitude for the worses cases. However, the rest
of the logic is noisy enough that it hardly matters for now.
Testing that convert.hg.preserve-hash=true can be used to make hg
convert from hg repo to hg repo preserve hashes, even if the
computation of the files list in commits change slightly between hg
versions.
$ cat <<'EOF' >> "$HGRCPATH"
> [extensions]
> convert =
> EOF
$ cat <<'EOF' > changefileslist.py
> from mercurial import (changelog, extensions, metadata)
> def wrap(orig, clog, manifest, files, *args, **kwargs):
> files = metadata.ChangingFiles(touched=[b"a"])
> return orig(clog, manifest, files, *args, **kwargs)
> def extsetup(ui):
> extensions.wrapfunction(changelog.changelog, 'add', wrap)
> EOF
$ hg init repo
$ cd repo
$ echo a > a; hg commit -qAm a
$ echo b > a; hg commit -qAm b
$ hg up -qr 0; echo c > c; hg commit -qAm c
$ hg merge -qr 1
$ hg commit -m_ --config extensions.x=../changefileslist.py
$ hg log -r . -T '{node|short} {files|json}\n'

Now that we have a commit with a files list that's not what the
current hg version would create, check that convert either fixes it or
keeps it depending on config:
$ hg convert -q . ../convert
$ hg --cwd ../convert log -r tip -T '{node|short} {files|json}\n'
b7c4d4bbacd3 []
$ rm -rf ../convert
$ hg convert -q . ../convert --config convert.hg.preserve-hash=true
$ hg --cwd ../convert log -r tip -T '{node|short} {files|json}\n'
c085bbe93d59 ["a"]
$ rm -rf ../convert
