Search via webdav includes root folder

[tobiasKaminsky]

I found a potential regression or at least a change of search syntax:
When I do a search for a user without any content, I do receive:
NC21: http 207 with empty multistatus
master, NC22: http 207 with root folder of this user
You can test this with:

curl --request SEARCH \
--url http://localhost/nc/remote.php/dav \
--header 'Content-Type: text/xml' \
--header 'OCS-APIRequest: true' \
--data '<?xml version="1.0" encoding="UTF-8"?>
<d:searchrequest xmlns:d="DAV:" xmlns:oc="http://nextcloud.com/ns">
<d:basicsearch>
    <d:select>
        <d:prop>
            <d:displayname />
        </d:prop>
    </d:select>
    <d:from>
        <d:scope>
            <d:href>/files/test</d:href>
            <d:depth>infinity</d:depth>
        </d:scope>
    </d:from>
    <d:where>
        <d:and>
            <d:is-collection />
        </d:and>
    </d:where>
    <d:orderby />
</d:basicsearch>
</d:searchrequest>'
