--n_genomes not working

[HadrienG]

the --n_genomes/-u option supposed to pick random genomes from fasta files seems broken:

iss generate --genomes SRS121011.fasta --n_genomes 5 --model novaseq --output novaseq_reads
INFO:iss.app:Starting iss generate
INFO:iss.app:Using kde ErrorModel
INFO:iss.util:Stitching input files together
INFO:iss.app:Using lognormal abundance distribution
INFO:iss.app:Using 2 cpus for read generation

Traceback (most recent call last):

    n = args.n_genomes[0][0]

After making the suggested changes on app.py it works but this time abundance.txt screws up. It appears like this, the list goes on
iss generate --genomes splitted.fasta --n_genomes 5 --model miseq --output hiseq_reads

Should be fixed with version 1.4.5 (available via conda any moment now).
