Consistent PDF generation in corner cases & No exit != 0 if few germline variants
- Now no exit code != 0 is raised if there are less than 50 germline variants in the tinda job.
- If less than 50 germline variants are found, now an PDF with a warning message is produced
- The germline-variant count was off by one (1 to much). This is fixed.
- If there are zero germline variants now a PDF with a warning message is produced.
