qdataurl: extend the unittests

Browse Source 
Check:
- data: urls with a host are treated as malformed
- if the mime type is omitted, it's set to
  "text/plain;charset=US-ASCII" as per the RFC[1]
- the mime type of urls with a `charset` attribute are
  normalized by adding "text/plain;" (Qt implementation detail) if it's
  missing
