Subject: [PATCH] context: make driver runnable when we add a runnable node
Explicitly make the driver runnable when we add a runnable node to it.
We have to do this because the runnable node might not be directly linked
to this driver.
In the case of the echo-canceler, for example, a playback stream
can be linked to the sink before the echo canceled virtual sink.
All echo-cancel nodes are added to a source driver, which would not be
activated because there is no direct path from the playback stream
to the source river.
Fixes #3145
