Initialize failure line groups as array. Issue #56

[numbata]

Failure line groups should be initialized as array in case of Rspec's ExceptionPresenter.

Fixes #56 issue.

Thanks for this. So what's weird is that all of the integration tests like the ones here pass, so I'm curious what's different about these tests vs. the test you wrote in which you managed to get this error. Can you add a new context to this file and use the existing tests there to create a new test that reproduces it? That way we know that your changes work.

@mcmire I added new spec with proof.

The exists integration tests do not cover the problem code inside "if". But this code can be executed in case of multiple exception error, that initiated with failure_lines option (Look here and around).

Thanks! I'll take a look later today. :)

This makes sense. Thanks for the patch!
