Fixed issue with single-chromosome mapping after the bootstrap fix and fixed error that occurred if either bootstrap or permutations were set to 0

* wqflask/wqflask/marker_regression/display_mapping_results.py - Cast self.qtlresults 'chr' as a string since the comparison between it and the chromosome names was faililng due to numeric chromosomes being int type + used a list comprehension that converts None to an empty string when creating a comma-joined string from the list of mapping output files
