Minor difference in oc:trashbin-original-location PROPFIND response

[phil-davis]

Steps to reproduce

1. have users Alice and Brian

2. Alice creates a folder shared with sub-folder sub and in that is file shared_file.txt

3. Alice shares folder shared with Brian

4. Brian deletes shared/sub

5. shared/sub/shared_file.txt appears in both the trashbin of Alice, and of Brian - good and expected

6. Alice queries her trashbin:
   REQUEST: PROPFIND http://172.17.0.1:8080/remote.php/dav/trash-bin/Alice

7. Brian queries his trashbin:
   REQUEST: PROPFIND http://172.17.0.1:8080/remote.php/dav/trash-bin/Brian

Expected behaviour

They both see the file shared_file.txt with the same value in oc:trashbin-original-location

Actual behaviour

Alice sees:
<oc:trashbin-original-location>/shared/sub/shared_file.txt</oc:trashbin-original-location>

Brian sees:
<oc:trashbin-original-location>shared/sub/shared_file.txt</oc:trashbin-original-location>

Alice has a leading / and Brian does not.

That may or may not break a client that wants to restore the file to its original location. But even if the clients are working OK, the difference is a bit odd.

I had to adjust the automated tests in #39336 to ignore this little difference, in order to get the overall tests to pass.

It might be better if the responses are consistent.
