Error trying the delete an entity

Problem/Motivation

If you try to delete an entity:

drush ed node 1 2 3 4 5

you will see this error:

 [error]  Error: Call to undefined function node_delete_multiple() in _drush_entity_delete_node() (line 1026 of /Users/adriancid/.drush/drush_entity/entity.drush.inc) #0 /Users/adriancid/.drush/drush_entity/entity.drush.inc(1002): _drush_entity_delete_node(Array)

Proposed resolution

The code need an update to the new Drupal 8 API functions.
Read more at:

https://api.drupal.org/api/drupal/core!includes!entity.inc/function/enti...

And as entity_delete_multiple() will be deprecated in Drupal 9, we need to use the EntityStorageInterface::delete https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Entity%21...

See a working example in:
