fix(Trash): Fix original location for deleting shared item

Fixes #3339

[provokateurin]

I'm not sure if there is a more common scenario to trigger this, so that the fix needs to be extended to other storages as well.

@provokateurin Thanks for the fix! Would it be possible to also get a backport to stable28? :)

[provokateurin]

No, unfortunately 28 is no longer supported at all. You should update to at least 29 to still receive security and bug fixes.

For some reasons the tests don't pass on 29 and 30, so I'm also not going to fix it on those versions and it will only be in the new 31 version that will be released in less than a month.
If you want you can try to find a fix for 29 and 30 (I expect them to have the same problem) and I'm happy to review those PRs if you manage to do it.
