    Google Calendar: remove child hack, improve alarm hack (FDO #63881)

    Google recently enhanced support for RECURRENCE-ID, so SyncEvolution
    no longer needs to replace the property when uploading a single

    broken in the server, with no workaround in SyncEvolution:
    - Removing individual events gets ignored by the server;
      a full "wipe out server data" might work (untested).
    - When updating the parent event, all child events also get
      updated even though they were included unchanged in the data
      sent by SyncEvolution.
    - The RECURRENCE-ID of a child event of an all-day recurring event
      does not get stored properly.
    - The update hack seems to fail for complex meetings: uploading them
      once and then deleting them seems to make uploading them again

    All of these issues were reported to Google and are worked on there,
    so perhaps the situation will improve. In the meantime, syncing with
    Google CalDAV should better be limited to:
    - Downloading a Google calendar in one-way mode.
    - Two-way syncing of simple calendars without complex meeting

    While updating the Google workarounds, the alarm hack (sending a
    new event without alarms twice to avoid the automatic server side
    alarm) was simplified. Now the new event gets sent only once with a
