-----------
StreamTeeState does not need to ref its branch streams

Reviewed by Chris Dumez.
It is unnecessary for StreamTeeUtilities to keep a RefPtr of branch1 and
branch2.
We replace them with WeakPtr, which reduces potential ref cycles.
In the pull algorithm, we can dereference the WeakPtrs into Ref as the pull
algorithm is called by the controller which is owned by the stream. This
therefore means that the stream is alive at the time the pull algorithm is
called.
Covered by existing tests.
