Title: XContentMapValues.filter now works with nested arrays

The filter method of XContentMapValues actually filtered out nested
arrays/lists completely due to a bug in the filter method, which threw
away all data inside of such an nested array.

Closes #2944
This bug was a follow up problem, because of the filtering of nested arrays
in case source exclusion was configured.
