super function call with spread argument

Closed username-removed-748031 requested to merge oliver.buchtala/buble:issue-129 into master

Trying to fix #129 (closed).

Here again the problem description: Transpilation of super.function(...args) calls is broken. The problem is that gets transpiled into something like (ref = A.prototype), ref, args)

My solution:

  1. Added a test case.
  2. CallExpression: Done in the same way as you treat super() calls, detecting cases like '', and setting superNode.noCall

Let me know if you think this is an adequate approach.
