* (Babylon) Fall back to non-strict mode

This makes Prettier a little less opinionated about linting. For
example, the following can now be formatted:

```js
function f(a,a){return a}
```

whereas before it would cause an error:

    stdin: SyntaxError: Argument name clash in strict mode (1:13)
    > 1 | function f(a,a){return a}
        |              ^

This also allows octal numbers to be parsed,
and therefore fixes https://github.com/prettier/prettier/issues/228

If the code parses neither as strict nor as non-strict, the error from the
strict parse is thrown (as it was before this change).

I noticed this while trying out [eslump] with prettier:

    eslump | pbcopy; pbpaste | prettier

* Add missing test

* Use Object.assign() instead of mutating object
