Executed HTTPS upgrade before notifying the start of the provisional load.
This makes so that the fetch URL sent to the browser process for
navigations with the start provisional load notification is already the
final, potentially HTTPS upgraded one. This caused some problems with
upcoming changes where the URL stored in the NavigationHandle differed
from the actual URL being navigated to. A new test is also added to confirm
the upgrade is executed as expected.
