Motivation
----------
It's a follow up to #10028. I think it would be better user experience if one can tell by the icon what the delete button is about to do.
I hope I caught all the occurences where one can permanently delete assets.
How to test
-----------
1. Visit e.g. `/trash`
2. If you select some assets, the delete button in the top right corner
looks different.
* fix: prevent trashing of trashed assets
Motivation
----------
This will improve user experience by hiding a pointless action.
You can not trash a trashed asset again. It won't get any trashier than it already is.
How to test
-----------
1. Visit route `/trash`
2. Click on an asset
3. Press "Delete" on your keyboard
4. Nothing happens
5. Try to find the trash button in the top right
6. You can't find it
