Fixed 'Missing Partial' problem in rails3 #44

[MhdSyrwan]

Fixes the rendering problem listed in issue #44 (comment)

ActionView::MissingTemplate - Missing partial sync/memo_replies/refetch/memo_reply with {:locale=>[:en], :formats=>[:json], :handlers=>[:erb, :builder, :arb, :slim, :coffee]}.

Cause:
because an issue in rails 3 rails/rails#4841
The partial always falls back to the response format (which is json in sync requests)

Solution:
Solved according to -this StackOverflow question- this way:

def show
   render json: {
    html: with_format(:html){ @partial.render_to_string }
   }
end
