    [hotfix][network,tests] Add new unit tests for ResultPartitionManager#createSubpartitionView
    
    It is necessary to make sure PartitionNotFoundException is thrown on producer side for flip1, so some new tests are added to cover the cases
    of creating subpartition view via ResultPartitionManager for registered/unregistered partitions.
