Problems with annotations like nonnull and lists in kotlin

[robp94]

Follow-up issue of #1366

There seems to be a discrepancy between client and server

@Query
fun test2(list: List<@NonNull String>): String

@Query
fun test3(list: @NonNull List<@NonNull String>): String

result in schema

test2(list: [String!]!): String
test3(list: [String!]!): String

But both test fail with

Variable type '[String!]' doesn't match expected type '[String!]!

I think that both server and client should fit together.
Furthermore, test1 is wrong in both client and server, but could be some kotlin problem.

@Query
fun test1(list: @NonNull List<String>): String

Graphql:

test1(list: [String]): String

Note kotlin is a bit special with annotations https://youtrack.jetbrains.com/issue/KT-35843 we need an extra flag.
