Fixes #3681.
Child LiveViews would use the same data-phx-stream-ref, so it could happen that they were cleared unexpectedly because we did not always check the owner of the stream element when pruning.
There was another issue at play though: because we used assign_new to set the streams, nested LiveViews would copy a parent's streams, instead of creating a fresh one. This would lead to mixed up streams in the dead render.
