Title: Fix issue where child comment would get vote of parent if parent deleted

when the initial load was looking for like/dislike, it was using `:first` to find the `.arrow` class. this normally worked but if the parent comment was subsequently deleted, it would find the first child comment's `.arrow`. changed this to look for `.arrow` class within the `.midcol` of the parent instead of just blindly grabbing the first one.

fix for #193
