+Bugfix: Fix search report
+
+There were multiple issues with REPORT search responses from webdav. Also we want it to be consistent with PROPFIND responses.
+*   the `remote.php` prefix was missing from the href (added even though not neccessary)
+*   the ids were formatted wrong, they should look different for shares and spaces.
+*   the name of the resource was missing
+*   the shareid was missing (for shares)
+*   the prop `shareroot` (containing the name of the share root) was missing
+*   the permissions prop was empty
