Allow translated properties for variant reporting experts

see https://jira.gsc.wustl.edu/browse/AT-556

This change is needed for the RNAseq report. While testing this change I also found bugs with the report and other components that were fixed as part of this pull request.
I wonder if it would be worthwhile to make standard accessors for the alignment results on both types of build like there are for the BAMs already (`tumor_bam` and `normal_bam`).

This isn't something you changed, but it confused me that this is called `@aligned_bams` but it's holding aligned bam results.
