[DSM] PEPPER-1408 Fix for Tracking Scan Duplicate Error

[pegahtah]

Context

The error was being thrown because after checking if the value exists the method still tried to insert the values and would get an exception. Fixed it and added a test

Checklist

• I have labeled the type of changes involved using the C-* labels.
• I have assessed potential risks and labeled using the R-* labels.
• I have considered error handling and alerts, and added L-* labels as needed.
• I have considered security and privacy, and added I-* labels as needed
• I have analyzed my changes for stability, fault tolerance, graceful degradation, performance bottlenecks and written a brief summary in this PR.
• If applicable, I have discussed the analytics needs at both a platform and study level with Product and instrumented code accordingly.
• If applicable, my UI/UX changes have passed muster with Product/Design via an over-the-shoulder review, screenshots, etc.

If unsure or need help with any of the above items, add the help wanted label. For items that starts with If applicable, if it is not applicable, check it off and add n/a in front.

FUD Score

Overall, how are you feeling about these changes?

• ☺️ All good, business as usual!
• 😅 There might be some issues here
• 😱 I'm sweaty and nervous

How do we demo these changes?

How does one observe these changes in a deployed system? Note that user visible encompasses many personas--not just patients and study staff, but also ops duty, your fellow devs, compliance, etc.

• They are user-visible in dev as a regular user journey and require no additional instructions.
• Getting dev into a state where this is user-visible requires some tech fiddling. I have documented these steps in the related ticket.
• Requires other features before it's human visible. I have documented the blocking issues in jira.
• I have no idea how to demo this. Please help me!

Testing

• I have added regression test labels to the jira ticket
• I have added verification steps to the jira ticket
• I have written automated positive tests
• I have written automated negative tests
• I have written zero automated tests but have poked around locally to verify proper functionality
• The jira ticket has acceptance criteria and QA has the needed information to test changes

Release

• These changes require no special release procedures--just code!
• Releasing these changes requires special handling and I have documented the special procedures in the release plan document

I don't think we need this annotation on a public method on a dao. It's general purpose.

Noted, will remove it!

[zyme]

No longer used?

[pegahtah]

Yes Sorry I meant to but forgot to put a comment about it, it is never used and also was throwing me off for more than 15 minutes of why is there an insert statement, so I thought better to remove this unused code.
