Pin scipy to less than 1.6.0 until ESMValGroup/ESMValCore/issues/927 gets resolved

[valeriupredoi]

Description

• Related to Test failure for tests/integration/cmor/_fixes/cmip5/test_bcc_csm1_1.py #927 - it doesn't close it, it addresses the test failure when the environment picks up scipy=1.6.0; the real closure needs to be addressed in the issue by identifying if the differences from the spline calculation are normal or not (I don't know this stuff)
• the test naming change is there because new FLAKE is complaining, see test result

Thanks, V! I think is pretty safe to do this as we are already working on solving #927

no because scipy gets installed from conda-forge

cool, cheers Javi! @bouweandela I am merging this since setup.py doesn't need to be changed 👍
