relationships needs a table_specific_uuid column

[dividor]

Describe the bug
The UI needs to have table_specific_uuid added back in for relationships tests as currently it's been removed. Tests do work if the table has a column 'uuid', but obviously this isn't good

To Reproduce
Steps to reproduce the behavior:

1. Add relationship test type for a table with no uuid
2. Run DOT
3. Will get a SQL error saying uuid doesn't exist

Expected behavior
User should be able to provide a uuid column
