⚡ Refactor ticket

Backend tests are slow, because the test DB is often cleared after each test of a suite. Seting up the database only once before and clearing it only after each suite reduces the test time by e.g. 60%.

Motive

Implementation

• fix before|afterAll, before|afterEach blocks in tests
