tests: demonstrate crash when trying to rebase merge without its parents

As the test case shows, when "hg rebase -d G -r 'B + D + F'" is run on
the following graph, we crash with traceback. It's reasonable to fail
because we can not easily produce a correct rebased F. The problem is
what diff to apply to either the rebased B or the rebased D. We could
potentially produce the result by e.g. applying the (F-D) diff to the
rebased B and then applying the reverse (E-D) diff on top, but that
could result in merge conflicts in each of those steps, which we don't
have a way of dealing with. So for now, let's just add a test case to
demonstrate that we crash (i.e. the AssertionError is clearly
incorrect since the user can run into it).

A fix directive from commit message is added to release notes

  $ touch fix1
  $ hg -q commit -A -l - << EOF
  > commit 1
  > 
  > .. fix::
  > 
  >    Fix from commit message.

Processing again ignores the already added bullet.

Sections are unioned

  -------------
  
  This describes a feature from a release notes file.

  This describes a feature from a commit message.

Doing it again won't add another section

  $ hg releasenotes -r . $TESTTMP/single-feature-section
  Commit Message Feature already exists in feature section; ignoring
