Zachary Tong a8a81200d0 Better support for unmapped fields in AggregatorTestCase (#43405)
AggregatorTestCase will NPE if only a single, null MappedFieldType
is provided (which is required to simulate an unmapped field).  While
it's possible to test unmapped fields by supplying other, non-related
field types... that's clunky and unnecessary.  AggregatorTestCase
just needs to filter out null field types when setting up.
