Expected Behavior

When making a change to the aws_appstream_fleet that causes it to be replaced e.g. changing from ALWAYS_ON to ON_DEMAND the stack association also needs to be deleted first and re-created.

Actual Behavior

No changes planned for the stack association, appstream fleet change fails
