Reuse project settings in dtos

[Slartibartfass2]

Closes #614

What I have made

This is a step-by-step refactoring:

1. Added ProjectSettings DTO and replaced the settings properties in Project with it
2. Replaced default project settings properties in UserSettings with single ProjectSettings property
3. UserSettings is now also stored in the User DTO
4. Only pass ProjectSettings instead of UserSettings to createProject repo call
5. Remove getUserSettings repo call and use settings from the user DTO directly

In DataBuilder I didn't change the parameters to pass a settings object in favor of a more simple fixture creation.
