Finish deflaking the net-internals prerender view test and split it in two.

Deflake and clean up the net-internals prerender view test.
It was occasionally timing out because I wasn't decreasing
BrowserBridge's polling timer.  That is now fixed.  Along
with some prerender history fixes, this should deflake the
test.
I've also split the net-internals prerender view test into
two tests, one for the success case and one for the failure
case.  This simplifies the test a little, and now the
success case visits the page.

BUG=91799
TEST=NetInternalsTest.NetInternalsPrerenderViewSucceed, NetInternalsTest.NetInternalsPrerenderViewFail

Thanks.

I'm hoping to land tests for a view or two a week until we have a fairly
complete set.  Not sure about testing any other files directly, other than
exporting/importing log files.
