- Removed "Principle". No longer using the concept of "owner".
- Removed "owner", both on the grid and the filter.
- Removed references to business owner. Fixed references to "contact" to correctly use the known relationship groups.
- Fixed the Contact List grid to only show if the business has been saved already. You can't add a contact to a business that doesn't exist.
- Added a migration to fix the group roles and attributes.
