Traceback thrown in SchemaArray.map with Node 6.x

[rconnamacher]

I'm getting a traceback when running on Node 6.10.1, but not on Node 4.x.

const SchemaObject = require('schema-object');
const Foo = new SchemaObject({
    name: {type: String}
});
const FooGroup = new SchemaObject({
    foos: {type: [Foo]}
});

const fooGroup = new FooGroup({
    foos: [{
        name: "Foo 1"
    }]
});

fooGroup.foos.map(foo => foo);
// Boom, see traceback below...

TypeError: Cannot read property 'arrayType' of undefined

@rconnamacher I'm looking into it. Thanks for the report.
