(maint) fix node report footer

Prior to this commit, when a node had more than 10 reports, the node
detail page would have a `nodes/report_table_tfoot` blurb rather than
actually rendering that partial view. This commit alters the call to
`render` so that the partial view is dereferenced and rendered.
