Capture http to https navigations w/ intent picker

For navigations from http to https we cannot rely on the Referrer's url
since it is cleaned due to the sanitization proccess. For this case we
will make use of GetLastCommittedURL(), the main purpose of this
information is to decide whether or not to register
ArcNavigationThrottle as a candidate to handle a given navigation.
