_.isFinite() gives wrong result for `true` and `[]`

I expect both results to be `false`

``` js
_.isFinite(true); // true
_.isFinite([]); // true
```

check [amd-utils/lang/isFinite](https://github.com/millermedeiros/amd-utils/blob/master/src/lang/isFinite.js) and [specs](https://github.com/millermedeiros/amd-utils/blob/master/tests/spec/lang/spec-isFinite.js) for reference.
