Remove unnecessary stream creation.

Sites like gmail, facebook, etc regularly result in a paused proxy
lurking in the background.  This results in the dispatcher always
opening one more stream than it needs and then closing it seconds
later.

This is wasteful behavior and should be removed.

This is part of https://codereview.chromium.org/27605002/, which
can't be landed yet due to issues around stream errors and stream
recycling.
