Do some aesthetic adjustments to role presentation fields

[AlanCoding]

SUMMARY

Firstly this is adding a test to assure we have Capital Letters.

We also want to be sure that anything that we ship has a description.

Most notably, this fixes an issues where an auto-created RoleDefinition would have created_by set, and we don't want that, because it shouldn't be attributed to such an (ordinary) user.
