Object predicate is currently only used by vectorized matchers for non-string object selectors. This currently means it will be used only if we encounter COMPLEX types, but will also include array types once they are more supported throughout the query engines. To preserve behavior with non-vectorized matchers which use a string predicate with null inputs for these 'nil' matchers, we do the same thing here.
