Attribute reference to 'bigwig' on Sample in chipseq.py

[vreuter]

In the chipseq.py pipeline, there are three usages of sample.bigwig, but the Sample instance being used does not have a bigwig attribute.

Target exists: `/sfs/lustre/allocations/shefflab/processed//kipnis_chip/micro/results_pipeline/input_12k/mapped/input_12k.trimmed.bowtie2.filtered.bam.bai`
Removed existing flag: /sfs/lustre/allocations/shefflab/processed//kipnis_chip/micro/results_pipeline/input_12k/chipseq_failed.flag

@afrendeiro where did we lose the bigwig attribute?

This is added now.

Actually, this is just solved in the databio fork...
