Subject: MqWebView: Invalidate main resource data cache on load change

Otherwise, a connected source view will keep getting the data the first
such view received, even after a load change.

A better solution would be to cache a pointer to the main resource and
check in mq_web_view_get_data() if the main resource's address has
changed.  But apparently WebKit reuses resource objects, so that doesn't
work.
