[KIO] Regarding KIO based redirection handling and header responses

[Dawit A]

Unless you explicitly disable internal redirection handling, you will never
be able to get the redirection HTTP header from kio_http if you are
attempting to read from a slot connected to KIO's "result" signal. Instead,
what you should try to do is connect to the "mimeType" signal and look for
the meta-data there.
