seqcluster: @Nilesh, please kindly revisit the testing

[Steffen Möller <steffen_moeller@gmx.de>]

Dear Nilesh,

I promise I barely touched anything but testing now fails. I presume
this is because of the advent of Python 3.9, but ... you are more of an
expert here.

The failure are missing files to test against. I am not sure if this is
because the build directories (3.8 vs 3.9) are somehow mixed up and
these files are generated or if this was always like this (don't think
so but upstream pointed out that some files may be distributed with
bcbio) or if you had done some magic on separate tarballs that have not
made it into pristine-tar. I have temporarily helped myself with a
dh_auto_test || clearscreen kind of trick and would submit nonetheless
to fix this later or not at all if bcbio is working as expected.

Many thanks for your input.

Best,

Steffen
