Refactor NewJobApplications

[aloraalee]

NewJobApplication.tsx should move the following code to the respective file:

• Delete commented-out line of code that are not needed
• Move 2 fetch calls to trackerApiCalls.tsx

It's possible the fetch calls already exist in apiCalls or trackerApiCalls and just need to be called in NewJobApplication with the correct data returned.

Remember to import in NewJobApplication
