Subject: [PATCH] Fixed multiple edit relationship bugs

- Fixed issue making it impossible to add new relationships until the page is refreshed after deleting an existing one (only when you refreshed the page after creating the initial relationship)
- Fixed NPE in DsDynamicLookupRelationModalComponent
- Grouped buttons on relationship page in order to assure that they always have the same behaviour
