modules: make a default node.link-group property

Browse source 
When nothing else is specified, add a default node.link-group property
so that all the nodes from this echo-canceler are tagged as being linked
together in some way.

This allows the session manager to follow the relations between the
different streams and avoids linking those related nodes together, which
avoids playing or recording from itself in a loop.

Fixes #1376
