rspec-parameterized 0.4.0 fails spectacularly with Ruby 2.5.3 with the
following error:

```
RuntimeError:
  No such frame, gone beyond end of stack!
```

This happens because of a Ruby bug in
https://bugs.ruby-lang.org/issues/15105.  The binding_of_caller gem
induces this failure. This upgrade switches to the binding_of_ninja gem,
which does not have the same problem.
