[RSN-38] - Create services (address, comment, objecttype, participant…

…, role, user*) (#19)

* Created services classes and added TODO methods for each class

* Created basic CRUD methods

* Changed methods returing types, checks for null

* Checks if user already exists in db etc., created tests for services

* Fixed unit test

* Changed type taken by the services, new, improved tests for services

* Final fixes and changed unit tests for methods with foreign keys

* Changed delete method to return bool, fixed typos and other problems based on PR review

* Added brackets one line ifs and added delete method for ObjectTypeService

* Revert "Added brackets to one line ifs, updated delete method in ObjectTypeService"

This reverts commit 1c69f11, reversing
changes made to 1a58a27.
