Note to reviewer: thoughts on updating the serialize behavior as well? See coerceFloat

Yeah - I think this change is actually more compelling for serializing than parsing input values.

Working on #1333 I noticed that you can pass arrays as scalars in a query variable, e.g. [SWAPI example](http://graphql.org/swapi-graphql/?query=query%20(%24id%3A%20ID)%20%7B%0A%20%20person(personID%3A%20%24id)%20%7B%0A%20%20%20%20name%0A%20%20%7D%0A%7D&variables=%7B%0A%20%20%22id%22%3A%20%5B1%5D%0A%7D) This PR is based on #925 but fixing same issue for types other than `String` e.g. ```js Number([1]) // 1 ```

Previously, we were using the default JS logic to coerce arrays to strings. This PR detects and disallows conversion of arrays into strings.
