Jouni Malinen ca8a51c4bb webkit2: Fix http://localhost:12345/ redirect handling
The resource-load-started cannot be used to replace the older
resource-request-starting signal and as such, the final redirect to the
special http://localhost:12345/ URL did not work. Use the decide-policy
signal for navigation action instead.

Also remove the attempt to modify the request URI from
resource-load-started since that is not going to work either. This is
not really critical for functionality, but could eventually be replaced
with a handler for the WebKitWebPage send-request signal.
