Failing tests

cc @dkillick, as this is very close to #2918 - not sure it is related though...

Scrap that @dkillick. This was caused by #3019.

I hear from @bjlittle that this test result is intermittent. This is also backed up with the fact that sometimes on master the test fails, but other times (e.g. 3034) it passes. This is really worrying, and points to a test order issue. I'll dig a little.

Have been able to reproduce on my mac using:

$ python requirements/gen_conda_requirements.py --groups test > conda-requirements.txt 
$ conda create -n iris-minimal --file conda-requirements.txt 
$ nosetests lib/iris/tests/unit/coords/test_CellMeasure.py -sv
