If owner is null, owner.get() throws null pointer exception

[arvind-das]

Even if the method is marked as deprecated, it is referenced in some other ORM tools like ferma, this method gets called and throws null pointer exception, can we fix this ? I can raise a PR

orientdb/core/src/main/java/com/orientechnologies/orient/core/record/impl/ODocument.java

Line 1910 in 901bc89

if (owner == null && owner.get() == null) return Collections.emptyList();
