trashbin of guest is empty when guest deletes a file/folder with files_trashbin not whitelisted

[PrajwolAmatya]

Steps to reproduce

1. set the guests whitelist so that files_trashbin is not in the whitelist
2. user Alice creates a folder temp and shares it with a new guest user guest@example.com
3. guest user uploads a file textfile.txt
4. guest user deletes file textfile.txt
5. guest user views the trashbin

Expected behaviour

textfile.txt to be available on trashbin

Actual behaviour

trashbin of guest user is empty

File textfile.txt deleted by the guest user is only available on the trashbin of user Alice

Also, guest users are able to delete shared files when files_trashbin app is not whitelisted. While trying to delete a shared file via UI a guest user cannot delete shared files when files_trashbin app is not whielisted.

@PrajwolAmatya see issue #525
In that issue reported that the file deleted by the guest does not appear in any trashbin (even Alice does not see the file in her trashbin)

Please confirm exactly what is the current behavior. Then we can all discuss what the requirement should be.

[PrajwolAmatya]

@phil-davis currently when the shared file is deleted by the guest user then the file does not appear in any trashbin. But when a folder is shared to the guest user by Alice and the files inside that folder is deleted by guest user it is available in the trashbin of Alice.
