WooCommerce API Manager 3.4.1

* Fix: PHP Fatal error: Uncaught Error: Call to undefined function Automattic\WooCommerce\Utilities\wc_get_container().

* Tweak: On Order edit update of Access Expires and/or Activations, process API cache refresh in task queue rather than immediately.

* Tweak: Don't delete API Key activations when WooCommerce Subscription transitions to on-hold then back to active status when payment is processed.
* Tweak: When WooCommerce Subscription changes status delete related Authenticated API cache.
* Tweak: Delete the Authenticated API cache for more events to cover edge cases where results may be stale when fresh results are needed.
