Restructure test for multi-line hash in method call to test against case
compatible with emacs <24.4

Unfortunately, multi-line hash/array syntax with arguments starting on a
new line looks a bit weird in emacs <24.4. In emacs 24.4 smie parser
handles this case a bit differently, it gives a bit more options to
customize rules. I think similar issue presents in other modes too, for
example in ruby-mode.
