Ring group announcement always has Answer() and Wait()

If you define a Ring group with an Announcement, the generated dialplan has an Answer() and a Wait(1) regardless of whether the channel is 'up' or not.

                    16. Answer()                                  [extensions_additional.conf:4594]
                    17. Wait(1)                                   [extensions_additional.conf:4595]
                    18. Playback(custom/know-your-ext-num)        [extensions_additional.conf:4596]

I believe these lines should be conditional on whether the channel has been answered yet or not as is done elsewhere such as for Announcements:

  's' =>            1. GotoIf($["${CHANNEL(state)}" = "Up"]?begin) [extensions_additional.conf:122]
                    2. Answer()                                   [extensions_additional.conf:123]
                    3. Wait(1)                                    [extensions_additional.conf:124]
     [begin]        4. Noop(Playing announcement Broadcast Message)
