RIM PR: 145660
Added manual test for testing the behavior of http authentication
challenge dialog. Both of these two files should be served over http.

RIM PR: 145660
Fixed a regression introduced by r111810, we should cancel the new
request when user press cancel button in http authentication challenge
dialog, and we should also allow sending empty username and password
with the request.
Also removed redundant codes which checked the existence of the
FrameLoaderClient pointer, as we've already moved authenticationChallenge()
out of class FrameLoaderClient, it is not needed.

Manual test added. Testing http authentication dialog relies on user interaction.
