* Addressbook/CardDAV: fix new Thunderbird 110 could not sync big addressbooks

Browse Source 
TB 110 does an initial PROPFIND and then requests ALL resources in a single multiget REPORT, which caused two problems:
a) enabled CalDAV/CardDAV request logging switched output-buffering on and then runs out of memory --> switching it and therefore logging off for multiget REPORTS with more then 200 resources
b) PROPFIND iterator wrongly continued running, if the not found resources together with the found ones exceeded the chunk-size of 500
