Match updated Observer interface

Description

interface Observer {

    // Recieves the next value in the sequence
    next(value);

    // Recieves the sequence error
    error(errorValue);

    // Receives the sequence completion value
    complete(completeValue);
}

const reducer = handleAction(ACITON_TYPE, {
  // Receives normal actions
  next(state, action);

  // Receives `error: true` actions
  error(state, action);

  // Receives `meta.sequence: 'complete'` actions
  complete(state, action);
});

Research direction

Locate the definitions of handleAction and handleActions in the redux actions source code. Identify the current method names used for handling normal actions, error actions, and completion actions. Rename them to `next`, `error`, and `complete` respectively, matching the Observer interface from the es observable spec. Update all related tests and ensure existing functionality is preserved. Refer to the issue description for the expected API.
