offer converters for comparisson

[vincemann]

i.E.:
compare(readModuleDto).with(savedModule)
.properties()
.all()
useConverter<Long,IdentifiableEntity>((a,b) -> {
if(b.contains("id")){
return a.equals(b.getId().toString())
})
.assertEqual();

will compare longs with propertynames containing "id" to respective entity.getId()

[vincemann]

otherwise looks more like this:
compare(readModuleDto).with(savedModule)
.properties()
.all()
.ignore(readModuleDto::getExerciseGroupIds)
.ignore(readModuleDto::getSchoolId)
.assertEqual();

    Assertions.assertEquals(objectGraphFactory.getSchool().getId(),readModuleDto.getSchoolId());
    Assertions.assertEquals(objectGraphFactory.getSchool(),savedModule.getSchool());
