[Bug 2109340] Re: Test suite failures: stderr confusion

[Julian Andres Klode]

** Description changed:

  [Impact]
- plucky+:
+ After fixing bug 2109339, tests in plucky fail due to a change in xvfb-run that now causes stderr to remain on stderr, and hence a Testsuite-Restriction: allow-stderr needs to be added.

- run that now causes stderr to remain on stderr, and hence a Testsuite-
- Restriction: allow-stderr needs to be added.
- 
- plucky and oracular:
- Also there are annoying "TestResult has no addDuration method" warnings that we should be fixing, these are really in nosetests, but let's just disable the warnings using:
- 
- PYTHONWARNINGS="ignore:TestResult has no addDuration
- method:RuntimeWarning"
- 
- so the log is easier to read.
  
  [Test plan]
  autopkgtests should succeed after upload, and not show warnings about addDuration missing anymore.
  
  [Where problems could occur]
  By allowing stderr we could not see regressions in new warnings, however that is not a regression, the tests did not work before, and when they worked, they were inadvertently rendered to stdout :D
+ 
+ [Other information]
+ Also there are annoying "TestResult has no addDuration method" warnings that we should be fixing, these are really in nose, see bug 2109342 for details.
