When an application creates a stream and doesn't specify a sink,
PulseAudio will try to use the default sink. If that doesn't work, the
stream creation fails instead of PulseAudio trying to find some other
sink that works.

To me it would make sense to be consistent in these two cases: creating
a new stream and rescuing a stream from a sink that is being removed.
If we care so much about keeping a stream alive that killing it is the
absolute last resort, then we probably should also try to find a
working alternative when the default sink doesn't work for a newly
created sink input. However, the simpler solution of just killing the
stream seems like an acceptable policy to me.
