ECA Processing Queued Task error
Problem/Motivation
When processing a task from the queue, \Drupal\eca_queue\Task::isDueForProcessing() throws an exception, "Typed property Drupal\eca_queue\Task::$time must not be accessed before initialization". This makes queue processing fail.
Steps to reproduce
Create a model that uses the ECA processing queued task event. Use an "Add to queue" action to add something to the queue. Run cron.
Proposed resolution
This is a regression from Commit 776e9526, for #3375167: PHPStand level 6 fixes. That commit added dependency injection to inject the time service, instead of calling it using the non-DI \Drupal::time() call.
The problem is, this task object is unserialized from the queue, and so its constructor is not called -- according to the docs for unserialize(), it explicitly skips the constructor.
Remaining tasks
We could implement an __unserialize() method to re-add the time service, but I'm thinking it's easier/cleaner to just revert to using \Drupal::time() -- I'm not aware of a standard way to do dependency injection on unserialized objects, so I would tend to go with the simpler solution rather than adding complexity here.
