Missing `cleanup` decorator in `test_subplots.test_exceptions`

[Kojoley]

pytest fails in test_subplots.test_subplots_offsettext because of missing cleanup, while nose is fine

[jenshnielsen]

Looks good. It might resolve some of the intermittent failures on Nose too

There seems to be a typo in the test comments # the pount of this test is to ensure that this raises. can you change that to point

@janschulz Any idea what happens to Appveyor here?

[Kojoley]

miktex has updated and something is wrong with them

[janschulz]

Is this also from miktex?

I think the easiest would be to pin miktext to the old version for now... Will add a PR for that... and then try to understand whats going wrong here :-/

[janschulz]

PW in #6744, will merge if that passes the appveyor tests
