Part of xx-code-review-comments.txt disabled

[Björn Tillenius]

The part that checks that the comment has been quoted in the text area is disabled, since it failed spuriuosly in buildbot:

  https://lpbuildbot.canonical.com/builders/lp/builds/897/steps/shell_7/logs/summary

It passed in ec2, and I can't reproduce it locally either. The failure message was:

Failure in test lib/lp/code/tests/../stories/branches/xx-code-review-comments.txt
Failed doctest test for xx-code-review-comments.txt

Failed example:
    print eric_browser.getControl(name='field.comment').value.replace(
        '\r\n', '\n') # doctest: -NORMALIZE_WHITESPACE
Differences (ndiff with -expected +actual):
      > This is a very long comment about what things should be done to the source
    + <BLANKLINE>
      > branch to land it. When this comment is replied to, it should wrap the line
