ZeroDivisionError with qualimap/rnaseq module

[drpatelh]

Description of bug

I hate to say it but I found another one of those ZeroDivisionError puppies after I upgraded MultiQC to 1.11 within the nf-core/rnaseq pipeline. I haven't changed the test data so maybe it was something introduced whilst fixing #1258 ?

Running multiqc -f . in the test data attached should reproduce the error.

File that triggers the error

test.tar.gz
