feat: Remove obsolete restrictions on prisma (#592)

#### Motivation and context

Since v5, where on unique queries exposes all the fields, not just
unique fields.

Reference:
https://www.prisma.io/docs/orm/reference/prisma-client-reference#filter-on-non-unique-fields-with-userwhereuniqueinput

#### Migration notes

<!-- Explain HOW users should update their code when required -->

### Checklist

- [x] The change come with new or modified tests
- [x] Hard-to-understand functions have explanatory comments
- [ ] End-user documentation is updated to reflect the change
