Subject: [PATCH] Removed usage of field.choices that triggered full table load
 (#8950)

Removed the `{{ field.choices|yesno:",disabled" }}` block because this triggers the loading of full database table worth of objects just to determine whether the multi-select widget should be set as disabled or not.

Since this "disabled" marking feature is not present in the normal select field, then I propose to remove it also from the multi-select.
