Don't consider vaccinations without a vaccination date as relevant for cases/contacts/eps

[MateStrysewske]

Feature Description

When creating vaccinations, the vaccination status of cases, contacts, and event participants of the associated person might be updated depending on the vaccination date.

Problem Description

Currently, vaccinations without a vaccination date update the vaccination status of ALL associated cases, contacts, and event participants to VACCINATED. However, that might lead to wrong data, which we have to avoid.

Proposed Change

• [x] Never update the vaccination status of cases, contacts, and event participants when a vaccination without a vaccination date is saved (see VaccinationFacadeEjb::updateVaccinationStatuses and the three VaccinationService::isVaccinationRelevant methods)
• [x] Always display vaccinations without a vaccination date as irrelevant (i.e. greyed out) in the vaccination lists
• [x] Change the info icon description of vaccinations without a date to the following: "This vaccination is not relevant for this case/contact/event participant because it does not have a vaccination date." Also add a translation to strings_de-DE: "Diese Impfung ist für diesen Fall/Kontakt/Ereignisteilnehmer nicht relevant, weil sie kein Impfdatum hat."
• [x] Adjust the tests accordingly (VaccinationFacadeEjbTest::testUpdateVaccinationStatuses). If there's no test case for this scenario yet, add one.
