Title: Close the correct pipelines when evicted from navigation context.

This has been wrong for a long time. Previously, only the pipeline associated with the root frame evicted would be shut down. 1) It shouldn't necessarily be closed, because there could be references to it still in the navigation context, and 2) Presumably none of the children pipelines of the root frame were ever exiting.

It's hard to test this right now because of #965.
