PROPFIND request to resource shared with user when deleted retains it's <oc:share-type> property

[S-Panta]

Describe the bug

When a resource is shared with a user and propfind is done to that resource from sharer with the body <oc:share-types />, the response will be 0. Even if the user is deleted, the value doesn't change. Same goes with the group. The value becomes empty only when the resource is unshared with the user or group but when they are deleted, the propfind property retains the previous value

Steps to reproduce

1. Create a user admin and einstein 2.create a folder test 3.Share the folder with einstein
2. Delete the user einstein
3. PROPFIND the resources by admin

 curl -k --location --request PROPFIND 'https://host.docker.internal:9200/remote.php/dav/spaces/a9439309-d04d-4855-8e66-aade543fa429%2478d13b96-8de1-4dfa-8886-c932831e6c04/testFolder' \
-uadmin:admin \ 
--data '<d:propfind xmlns:d="DAV:" 
            xmlns:oc="http://owncloud.org/ns" 
            xmlns:ocs="http://open-collaboration-services.org/ns">
    <d:prop>
        <oc:share-types />
    </d:prop>
</d:propfind>
'

Expected behavior

The XML response for sharetype should be empty

Actual behavior

<d:multistatus xmlns:s="http://sabredav.org/ns" xmlns:d="DAV:" xmlns:oc="http://owncloud.org/ns">

                </oc:share-types>
            </d:prop>
