Description

In FLINK-19681, UnalignedCheckpointITCase was updated to put more backpressure.

This revealed a bug introduced in FLINK-19907: resultPartitions can be requested before the operator chain is initialized.

A proper fix would be to initialize the chain after the outputs but before the inputs.
