1. timers: refactor setImmediate error handling …

   If an error is encountered during the processing of Immediates, schedule
   the remaining queue to finish after all error handling code runs (if the
   process is still alive to do so). The new changes make the Immediates
   error handling behaviour entirely deterministic and predictable, as the
   full queue will be flushed on each Immediates cycle, regardless of
   whether an error is encountered or not.
   
   Currently this processing is scheduled for nextTick which can yield
   unpredictable results as the nextTick might happen as early as close
   callbacks phase or as late as after the next event loop turns Immediates
   all fully processed. The latter can result in two full cycles of
   Immediates processing during one even loop turn.
   
   The current implementation also doesn't differentiate between Immediates
   scheduled for the current queue run or the next one, so Immediates that
   were scheduled for the next turn of the event loop, will process
   alongside the ones that were scheduled for the current turn.
