Title: except nil in state ivars.

ruby-2.0.0preview1 isn't working with Hash[[nil, ...]]. example for:

```
test: A TestCase #view_assigns should return the instance variables from the last #render_cell. (TestCaseTest):
ArgumentError: wrong element type (expected array)
```

Because ruby-2.0.0 validates wrong argument when use Hash[] now. I fixed it.
