> Phoenix adding multiple coprocessors for a table and one of them has preAppend and preIncrement
implementation and bypass the operations by returning the results. But the other coprocessors
which doesn't have any implementation returning null and the results returned by previous
coprocessor are override by null and always going with default implementation of append and
increment operations. But it's not the case with old versions and works fine on bypass.
