Recursive input type breaks if wrapped in a list

[kaqqao]

The following scenario seems to break:

type Query {
    allLinks(filter: LinkFilter): [Link]
}

input LinkFilter {
    OR: [LinkFilter!]
    description_contains: String
    url_contains: String
}

And the LinkFilter POJO:

public class LinkFilter {

    private List<LinkFilter> OR;
    private String description_contains;
    private String url_contains;

    //getters & setters
}

The exceptions is:

com.coxautodev.graphql.tools.SchemaClassScannerError: Two different classes used for type LinkFilter:
- class com.something.LinkFilter:
| parameter 0 of method public java.util.List com.something.Query.allLinks(com.something.LinkFilter)
- interface java.util.List:
| input object InputValueDefinition{name='OR', type=ListType{type=NonNullType{type=TypeName{name='LinkFilter'}}}, defaultValue=null, directives=[]}

If I unwrap the OR field to just a LinkFilter, everything is fine.

Ah, I think I forgot about lists in input types. I'll apply the same unwrapping logic to input fields

I gave fixing this a shot at #37, but it's my first time seeing Kotlin (or this code-base) so...
Feel free to reject and rewrite if it's bad. I ticked "allow edits from maintainers" in case you find some value in it.

Not sure, if you saw my Gitter message. The TLDR version is: I'm writing a tutorial for a new GraphQL learning portal by Graph.cool and used this lib in all the examples and the sample project in the Java track. The deadline is in 2 days, so I was trying to get this fix in time if possible. If not, I'll try working around this issue in the examples somehow.
