Introduce IdentifierAccessor.getRequiredIdentifier() [DATACMNS-1015]

[spring-projects-issues]

Oliver Drotbohm opened DATACMNS-1015 and commented

In some cases it might be necessary to access the identifier and immediately fail if there's no value available (e.g. in MongoTemplate.doSaveVersioned(…)). We should add a default overload of getIdentifier() to avoid clients having to deal with Optional themselves
