DEV: add more tests for future-date-input-selector (PR #13836)

This PR contains only tests. These tests are from my old PR with refactoring of future-date-input-selector. That PR was closed because we had some changes in our planes about our time-pickers and additionally these tests were flaky.

Tests in this PR aren’t flaky, since they use fake time moments in the future. Tests just document current behaviour of future-date-input-selector.
