Subject: Newly configured Google calendar cannot be opened

Unless the button to choose a calendar was clicked, because
the calendar path is not filled, thus the server claims
"HTTP 405 error", which means an OPTIONS request cannot be done
on the path, which was just root of www.google.com, instead
of a calendar path. (This was reported as part of bug #659522.)
