Ensure that array always have "items" attribute.

Implement based on comments from #404

It passing all JS test, but fails somewhere inside Scala tests.
I don't have any Scala knowledge to fix it :(

@IvanGoncharov - thanks, I'll review it and the tests. If the change is good, I'll work on the tests. It'll take a while though.

[IvanGoncharov]

I review Scala tests and they are very simple.
Is there are any reasons why they implemented in Scala?
They could be easily replaced with 30-40 lines in JS.
It could be easier than fix bugs in abandoned library:

[webron]

Knowing the library's author, I also know the project is not abandoned.

[IvanGoncharov]

So how about moving these test into https://github.com/swagger-api/swagger-spec/blob/master/test/validate.js ?
I can create separate PR.

[webron]

Sure, but unfortunately it would take me a while to review it.

[IvanGoncharov]

I understand.
I will create separate PR and link it to this.

[webron]

Thanks!

@IvanGoncharov - any update on this?

[IvanGoncharov]

@webron Just started migrated tests.
Problem that for some reason I can't run even vanilla tests on my machine :(
I will create separate issue with WIP status.

[webron]

@IvanGoncharov - closing this for now. Really trying to minimize changes to things related to 2.0.
