Fix scripts that have comments on their pulls.

 There are several things with the .minibutton class, filter them first

To reproduce: go to a pull request with no comments for the first couple files, then some after that. Using the old version, you'll only get edit links for the first couple files, and no edit links after the first comment.

This fixes that.
