Fixes #7861

Checklist

• Self-review the PR after opening it to make sure the changes look good and
  self-explanatory (or properly documented)
• Add relevant issue to release milestone
• Add pr to documentation list
• Add automated tests

Testing instructions

• Use a db created with the guided setup in Specify 7
• Make sure creating a user doesn't cause a crash
• Open up an existing database made in Specify 6 in Specify 7
• Make sure creating a user doesn't cause a crash in Specify 7
• Make sure creating a user in the existing DB properly creates Specify 6 permissions. You can verify this by logging into the user in Specify 6 (if you make them a manager in 7, it should work when you log into them in 6). If it works when creating it through v7.11.2, then it should work when creating it with this PR.
