Fix URL linkification test cases for addition of 'title' attribution with long URL...

After removing 103 false positives, this leaves 4 actually broken tests, showing two failure modes for mail links:
* 'mail without mailto' formatting shortcut in common_linkify didn't get the 'title' attribute added with the other URLs
* links including mailto: protocol are being incorrectly expanded to http: protocol in the long URL
