calcurse-caldav: always request href from server
Apparently, while some CalDAV servers return href values as is in their response, some might return them URL-quoted (which, if I am not mistaken, was the reason for e943b06). Assuming either behaviour when pushing local objects will lead to discrepancy with events dictionary retrieved from the server and thus bugs, hence we always want to use whatever form of href the server returns. Addresses GitHub issues #337 and #356. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
