Subject: [PATCH] Fix call to undefined function Fixes Issue #23

While working on porting entity_translation, I found a call to an
undefined function entity_ui_clone_entity(). I didn't see any other
entity clone functions in backdrop core entity or entity_plus so I chose
to copy the code directly from the Drupal 7 version.
