Import Issues doesn't work when you are an administrator of a Project

Steps to reproduce:

  1. Login as an administrator to a project in Jira
  2. Fill in the CSV file with the relevant detail
  3. Leave the reporter field blank

Actual Behaviour: Error is shown next to reporter

Expected Behaviour: Data import to complete successfully

Additional Information: I tried removing myself as an Administrator in the Jira Project and the upload worked like a charm. It also works when I assigned myself as a Resource person. I was able to reproduce this issue multiple times, after clearing cache etc.
