Fixed voting bugs

#70066648 

Fixed a few small things:

- Child comments are now ordering
- Cannot vote unless logged in
- When creating a comment, it automatically upvotes for you
- UI: changes from upvotes to upvote to upvotes when going from 0 upvotes to 1 upvote to 2 upvotes and so on...
Hah, whoops! Was a late night and didn't clean after myself. :P
