Multi-line error messages are rendered in a weird order

[4kochi]

Try this:

expect('Hello\nWorld').toBe(0);

The displayed error message is:

FAILED TESTS:
  myTest
    myOtherTest
      ✖ should work
        PhantomJS 1.9.8 (Mac OS X)
      World' to be 0.
      Error: Expected 'Hello
          at /var/folders/(...)/blablabla-test.js:126:0

The problem is that in the function getRelevantStackFrom(stack) the stack is splitted by \nand when the stack also contains the error message the output is formatted wrong in the function formatFailedStep(step)
