Subject: [PATCH 1/2] fix: include registered extra props in PROPFIND request
 body

registerExtraProp() registered properties for response parsing but
buildPropFindBody() never included them in the PROPFIND request XML.
Extensions using registerExtraProp() would never receive their
custom properties because the server was never asked for them.
