remove no-ssr, which was not necessary and causing the edit field not to appear the majority of the times visiting a Post.
this was really bad user experience since a user would need to refresh the page to comment.
removed args in refetchPostComments as there are no params passed in when it is called anymore
needed to add an if statement since if there are no comments on a Post, then this.$apollo.queries.Post is undefined and it errors out trying to call refetch()
