    DRILL-5523: Revert if condition in UnionAllRecordBatch changed in DRI…

    …LL-5419
    
    If condition in UnionAllRecordBatch which was changed to correct one in DRILL-5419 but
this change caused the regression (DRILL-5521).
    The root cause is not in change itself but rather in missing indication of child column
in map types when it is null. There is a big project upcoming re-working json reader implementation,
including map types (DRILL-4824) which will fix the problem.
    So far reverting change to initial state so users won't see the regression till DRILL-4824
is merged.
