life.qbic.datamodel.people.Address can contain null

[KochTobi]

The Address class has a default constructor and can return null on values leading to NullPointerExceptions. Example for an address containing null below.

long imageId = imageInfo.getImageId();
ImagingHardware hardware =new SRMHardware.Builder("some objective", new Detector("dummy detector")).build();
Location dummyLocation = new Location("13", new Address());
Instrument dummyInstrument = new Instrument("test_manufacturer", "Donnerblitz 2001", "db-2001-hp.5", dummyLocation, "DUMMY", hardware);
omeroClient.associateInstrumentWithImage(dummyInstrument, imageId);

It would be better to set default values of empty Strings using the default constructor or a builder pattern to avoid Nullpointers from occurring in the DTO.

@luiskuhn this is also relevant in the context of Omero instrument annotations because the Instrument DTO uses this class in its location.
