Disabled caches throw an exception on null return value #216

When com.blossomproject.core.common.dao.GenericReadOnlyDaoImpl#getOne returns "null" and its cache is disabled, the method fails with:

java.lang.ClassCastException: class org.springframework.cache.support.NullValue cannot be cast to class com.blossomproject.core.common.entity.AbstractEntity
