Fix finding the WebContents of a pending renderer process

Browse source 
Apparently after Chrome 44 a renderer process can be started before the
corresponding render view is created, though it can be patched but from
the source code Chromium is enforcing this everywhere now, so fixing it
on our side seems the only reliable solution.

This fix is very similar to what we did, but instead of blindly setting
swapped process, we now remember which process the pending process is
going to replace, so we should not have those race conditions.
