    [FLINK-9063] Fix SpillableSubpartitionTest testSpillFinishedBufferConsumers

    testSpillFinishedBufferConsumers was incorrectly manually closing the 
BufferConsumer
    after passing it's ownership to the ResultSubpartition. This was leading to 
a race
    conditions with AsynchronousBufferFileWriter.
    
    This is a change in tests that improves stability.
