Handling each exception specifically

[DavidStreid]

Removing large try-catch block

• Using UpdateLimsSampleLevelSequencingQcTask to handle DataRecord access
• Wrapping dataRecordManager.storeAndCommit in separate try-catch block

ALSO: Removing

            if (existingQc == null) {
                log.info(String.format("Existing %s record not found for Sample with Id %s", SeqAnalysisSampleQCModel.DATA_TYPE_NAME, igoId));
            }

Moving to else condition,

            if (existingQc != null) {
               ...
            }
            else {
                log.info(String.format("Existing %s record not found for Sample with Id %s", SeqAnalysisSampleQCModel.DATA_TYPE_NAME, igoId));
               ...
            }
