Plot scatter body introduces repeated points if GRanges are not deduplicated

[cnluzon]

This is a very specific and unusual case. If provided BED file has redundant loci, at some point in the merging the values are duplicated, creating spurious points. In the plot this does not matter but in the point-count it does.

This would be solved by deduplicating the BED file beforehand, which can be a bit costful but perhaps worth it.
