> In a special case the FilterList with MUST_PASS_ONE operator doesn't work correctly:
> - a filter in the list is a SingleColumValueFilter with filterIfMissing=true
> - FilterList.filterKeyValue(KeyValue) is called
> - SingleColumValueFilter.filterKeyValue(KeyValue) is called
> - SingleColumValueFilter.filterKeyValue(KeyValue) returns ReturnCode.INCLUDE if the KeyValue doesn't match a column (to support filterIfMissing)
> - FilterList.filterKeyValue(KeyValue) immediately returns ReturnCode.INCLUDE, remaining filters in the list aren't evaluated.
> However it is required to evaluate remaining filters, otherwise filterRow() filters out rows in case the filter's filterKeyValue() saves state that is used by filterRow(). (SingleColumValueFilter, SkipFilter, WhileMatchFilter do so)
