Fix: Specify calendar rather than random selectionfix/require_calendar_url

Without this commit, the calendar that gets used is undefined. With at
least some CalDAV implementation this practically means one is randomly
selected at every run. Having determinism at the small cost of required
configuration is the user expected behaviour for anyone using an account
with more than one calendar.
