Trash Broken for Product Variants and Folders🔵

Testing notes for PSBN-254:

Open the folder form page (with assets linked to it) and a product variant form page (with assets linked to it)

Select the assets on both pages.

Check that the selection toolbar has the same items for both pages.

Check that the toolbar items are working. (The trash functionality is broken even for the live site. We need another task to check this.)
