enable working object id test

[pjfanning]

see #4642

I couldn't find any issue relating to the broken tests - there are still 3 broken tests in ObjectIdDeserializationFailTest

Note: passing tests should be moved to

src/test/java/com/fasterxml/jackson/databind/objectid

instead of main src/test/java/com/fasterxml/jackson/databind/deser.

But I don't see much benefit in splitting cases here, as per my other notes.
