    [FLINK-7949] AsyncWaitOperator is not restarting when queue is full

    Emitter thread is started BEFORE filling up the queue of recovered elements
    Issue description:
    During process restart, if the queue was full (with N elements) and there was pending
element waiting to be added to the queue, then the queue couldn't fit N+1 elements and thread
was blocked forever. As Till Rohrmann suggested here:
    I've changed the order of this code to start emitter thread earlier.
