unbundle: add a small comment to clarify the 'check_heads' call

Bundle2 has its own mechanisms to check for heads (and other) changes, so push
using bundle2 is relying on the "check:heads" bundle part of unbundle and the
'check_heads' call is not checking anything. We add a small comment to make
this clearer.

Check that graphlog detect that a changeset is obsolete:

  $ hg log -G

  |
  o  1:7c3bad9141dc (draft) [ ] add b
  |
  o  0:1f0dee641bb7 (draft) [ ] add a
  

check that heads does not report them

  $ hg heads
  5:5601fb93a350 (draft) [tip ] add new_3_c
  $ hg heads --hidden
  5:5601fb93a350 (draft) [tip ] add new_3_c

  3:cdbce2fbb163 (draft) [ ] add new_c

check that summary does not report them

  $ hg init ../sink
  $ echo '[paths]' >> .hg/hgrc
  $ echo 'default=../sink' >> .hg/hgrc
  $ hg summary --remote
  parent: 5:5601fb93a350 tip

   add new_3_c
  branch: default
  commit: (clean)
  update: 3 new changesets, 4 branch heads (merge)
  phases: 6 draft
  remote: 3 outgoing

check that various commands work well with filtering

  $ hg tip

  $ hg log -r 6
  abort: unknown revision '6'!
  [255]
  $ hg log -r 4

  (use --hidden to access hidden revisions)
  [255]
  $ hg debugrevspec 'rev(6)'
  $ hg debugrevspec 'rev(4)'
  $ hg debugrevspec 'null'
  -1

Check that public changeset are not accounted as obsolete:

  $ hg --hidden phase --public 2
  $ hg log -G
  @  5:5601fb93a350 (draft bumped) [tip ] add new_3_c
  |
  | o  2:245bde4270cd (public) [ ] add original_c
  |/
  o  1:7c3bad9141dc (public) [ ] add b
  |
  o  0:1f0dee641bb7 (public) [ ] add a
  

And that bumped changeset are detected
--------------------------------------

If we didn't filtered obsolete changesets out, 3 and 4 would show up too. Also
note that the bumped changeset (5:5601fb93a350) is not a direct successor of
the public changeset

  $ hg log --hidden -r 'bumped()'
  5:5601fb93a350 (draft bumped) [tip ] add new_3_c

And that we can't push bumped changeset

  $ hg push ../tmpa -r 0 --force #(make repo related)

  [255]

Fixing "bumped" situation
We need to create a clone of 5 and add a special marker with a flag

  $ hg summary

   add new_3_c
  branch: default
  commit: (clean)
