test_to_picard_basecalling_params_output_files fails on MacOS

[dsommer]

Running the test suite on the master branch fails on MacOS.
I am running MacOS Monterey 12.2.1 on a INTEL mac with python 3.7.

pytest Error:

E           AssertionError: 'BARC[68 chars]TC\t/System/Volumes/Data/home/user/49-tissue.e[278 chars]\t\n' != 'BARC[68 chars]TC\t/home/user/49-tissue.exp001/49-tissue.GAAC[218 chars]\t\n'
E           Diff is 748 characters long. Set self.maxDiff to None to see it.
