topic: add more branchcache entries to test-topic-flow-publish-flag.t

It seems these new entries started appearing after the recent-ish refactoring
of branchcache in core. Now the server and the client have the same branch
cache data on disk, which is probably for the best.

The actual output with changeset hashes is:
branch2-base:c0155e8ec55a9b46d415d5b13a319d0c80e26e9d o double//slash
branch2-immutable:c0155e8ec55a9b46d415d5b13a319d0c80e26e9d o double//slash
branch2-served:256a2cb64fd8ada4ff18d57606d212f094cb50fb o double//slash

c0155e8ec55a is public, so it's correct to be in "base" and "immutable" repo
views. 256a2cb64fd8 is draft (without topic), so it's expected to be in the
"served" view.

======================================================
Tests the resolution of content divergence: relocation

This file intend to cover case where changesets need to be moved to different parents

Testing resolution of content-divergent changesets when they are on different

In this case, we have two divergent changeset:
- one did not changed parent
- the other did changed parent

So we can do a 3 way merges merges. on one side we have changes (the parent
change) and on the other one we don't, we should apply the change.

Testing when relocation results in nothing to commit
----------------------------------------------------

Set up a repo where relocation results in no changes to commit because the
changes from the relocated node are already in the destination.

  $ hg init nothing-to-commit
  $ cd nothing-to-commit
  $ echo 0 > a
  $ hg ci -Aqm initial
  $ echo 1 > a
  $ hg ci -Aqm upstream
  $ hg prev -q

Create the source of divergence.
  $ echo 0 > b
  $ hg ci -Aqm divergent

The first side of the divergence get rebased on top of upstream.
  $ hg rebase -r . -d 'desc("upstream")'
  rebasing 2:898ddd4443b3 tip "divergent"
  $ hg --hidden co 2 -q
  updated to hidden changeset 898ddd4443b3
  (hidden revision '898ddd4443b3' was rewritten as: befae6138569)
  working directory parent is obsolete! (898ddd4443b3)

The other side of the divergence gets amended so it matches upstream.
Relocation (onto upstream) will therefore result in no changes to commit.
  $ hg revert -r 'desc("upstream")' --all
  removing b
  reverting a
  $ hg amend --config experimental.evolution.allowdivergence=True
  2 new content-divergent changesets

Add a commit on top. This one should become an orphan. Evolving it later
should put it on top of the other divergent side (the one that's on top of
upstream)
