Title: Fix minor issue in fhe io.fits tests

Fixes a minor issue in the tests where if run in a specific order the FitsHDU tests could fail due to modification of global state by one of the other tests.

This occurred, seemingly randomly, in some of the test configurations on Windows. I haven't even been able to reproduce it myself, but this is the fix at any rate.
