[PATCH] Don't send interleaved byebye/alive on startup

[Jens Georg <mail jensge org>]

According to UPnP CTT, there should not be any byebye message after
the device sent an alive message. So we need to group the initial
byebye messages (also requested by the tool, UDA-1.1.3) to come
before the initial alive messages.

Partially fixes UDA-1.1.1 - UDA-1.1.1
