Prevent leaking RenderProcessHosts from PasswordManagerHandlerTest.

Prevent leaking RenderProcessHosts from PasswordManagerHandlerTest.

PasswordManagerHandlerTest should extend ChromeRenderViewHostTestHarness
so that it can create a TestWebContents without accidentally creating a
real RenderProcessHost. If this happens it is leaked to later tests
running in the same process and results in all kinds of nasty and hard
to track down use-after-frees.
