oc-calendar: force cache synchronisation for a message before aborting

Browse Source 
Sometimes we're trying to get the `objectVersion` of a calendar message,
but this message's entry is not in the cache. The method
`synchroniseCache` won't work in this case, so we try to force the
synchronisation of that particular message in order to get the change
number before aborting.
