Correct redirection to comment section for comment notification

Fixes #1960 #1961 and #1962

I did fixed the problem of redirecting to the comment section after clicking on name/time in notification comment view. 
The problem was caused that internal data says that the link of the comment is http://..../...#comment-42 which is correct url, but during redirection the comment information is lost. I was not able to find where it exactly get lost (somewhere around login into wp.com at corresponding webview), so my solution is replacing the url with http://.../.../#comment-42 as is used elsewhere and it is working now.

I also make time button tapable as requested in #1961
