Reviewed by J Pascoe.

When a same-site redirect was received when navigating an iframe, we would
resend the TransitionToLocal message causing an assertion.  This message is
not needed if there is already a local frame in the process.

I also moved a lot of the process preparation code from ProvisionalFrameProxy's
constructor and WebPageProxy to a new-ish function prepareForProvisionalNavigationInProcess
which is just expanding what used to be called "swapToProcess" to handle more cases.
