Dashboard comment and issue text truncation breaks links

Created by: bbodenmiller

If a user enters a comment on an issue with a link and the link text happens to be partially truncated the link breaks.

1. Create a new issue
2. Comment on the issue with test with url http://demo.gitlabhq.com/diaspora/diaspora/issues/422 test with url http://demo.gitlabhq.com/diaspora/diaspora/issues/422 http://google.com
3. View dashboard, try clicking http://goog

Notice that clicking the link tries to bring you to http://goog/ which does not exist, even though the text is truncated the link should still work.

Tested in 5.1.0 20df7b1 on http://demo.gitlabhq.com/
