CAPEDWARF-134 Must throw IllegalArgumentException when querying on KEY property with Key in wrong namespace
Add test to see if query considers current namespace when it is created (and not when it is prepared or executed)
Make sure FilterNamespaceChecker uses the query's namespace (not the current namespace)
CAPEDWARF-135 Iterator returned by PreparedQuery.asIterator throws IOOBE instead of NoSuchElementException
