Subject: [PATCH] default-nodes: Never consider Audio/Sink nodes as best for
 default audio.source node type

Audio/Sink nodes should only be used as default audio source node type if the
user has explicitly selected it. If the user has not explicitly selected it,
we should always ignore it and instead select the highest priority Audio/Source
node.

Fixes #886
