remove BUSCO warning from stdout log

[Lumimar]

Description of feature

at the moment BUSCO's no gene warning is reported in the STDOUT log where pipeline errors are normally highlighted, but given that it is expected that this might happen in some cases it might be better to remove the warning. Currently the warning is displayed like this (lines 3-7) at the end of the run:

[c6/eb468a] process > NFCORE_MAG:mag:CUSTOM_DUMPS... [100%] 1 of 1 ✔
[c3/8aa445] process > NFCORE_MAG:mag:MULTIQC         [100%] 1 of 1 ✔
-[nf-core/mag] For 2 bin(s) BUSCO did not find any matching genes:
    SPAdes-MaxBin2-test_minigut_sample2.noclass.2.fa
    SPAdes-MaxBin2-test_minigut_sample2.noclass.1.fa
See /home/lmarcell/out/GenomeBinning/QC/BUSCO/[bin]_busco.log for further information.-
