Review unit and UI tests for Menu, IPP and POS

[malinajirka]

Goal of this task is to review existing tests for Menu, IPP and POS and create sub-issues for tests that need to be added. All the features should have at least smoke-unit-tests (checking visibility of the item and basic functionality). UI tests are discussable as we don't want to cover all flows with UI tests, but we should have at least a basic smoke test for the POS, IPP and likely a couple more vital flows.
