"Plugin (order_tag) instance class "Drupal\commerce_order_tag_condition\Plugin\Commerce\Condition\OrderTag" does not exist. when uninstalling module

Problem/Motivation

When uninstalling and there's a commerce promotion using this condition, it leads to:
Uncaught PHP Exception Drupal\Core\Entity\EntityStorageException: "Plugin (order_tag) instance class "Drupal\commerce_order_tag_condition\Plugin\Commerce\Condition\OrderTag" does not exist.

Steps to reproduce

• Add an order tag condition in any promotion.
• Uninstall the module.
• Above error appears.

Proposed resolution

Remove the condition from promotion prior to uninstall, so install file there.
