Warning: Undefined array key "class" in Drupal\islandora_group\Utilities::isCalledFromBulkBatch()

[Natkeeran]

The following error is being thrown when editing menus metadata.

Warning: Undefined array key "class" in Drupal\islandora_group\Utilities::isCalledFromBulkBatch() (line 720 of modules/contrib/islandora_group/src/Utilities.php).

https://github.com/digitalutsc/islandora_group/blob/2.x/src/Utilities.php#L720

A quick workaround is to put in a isset check to see if the key class exists.
