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 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).

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

Using the same database I made with Specify 7:

• Make sure creating a user 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).

Hmm...

I'll leave it as note here to keep everything connected.
Databases created with the Setup Tool in Specify 7 are completely incompatible with Specify 6.

It may be intentional, but I'll leave it here as a note. Since #6389, Specify 6 is completely incompatible with databases created in Specify 7.
(If we haven't already, we'll need to update the docs marking the breaking of compatibility from 6 and 7).

#6671 (comment)

Those testing instructions should probably be something more along the lines of:

• Use a DB created with Specify 7's guided setup

• Make sure creating a Specify User does not cause a crash

• Use a DB created with the Specify 6 Wizard

• Create a user in Specify 7

• Login as the created user in Specify 6 and ensure their Specify 6 permissions were set

... Which is already the case in the PR which supersedes this one: #7868
