fix: application submitted page not being shown due to failed confirmation check. (#780)

- forgotten account confirmation check on the findSelf function in the hacker middleware allowed constant 409 requests.
- IMPORTANT: this issue has a ripple effect in the sponsor and volunteer middleware from what i understand as the code is the same in the findSelf functions in both classes.
  - i would recommend patching both or resolving the e-mail billing issue before the sponsor and volunteer onboarding.
