RIM PR: 158892

Way to reproduce:

navigate to any site which needs http authentication, input something or cancel
it directly. Then you'll see the webviews process crash.


Root cause:
We release the m_handle in the old network job too early before we start a new one with authentication information attached. when the m_handle has been passed to the new network job and the old one received a dataReceivedNotify (e.g. parsing the body data received together with 401 header), the crash happens.
So we should make sure that we cancel the current network job first, and then start the new one. by doing this we can avoid receiving a dataReceivedNotify after we start the new job.
