Non-recursive types are treated as recursive

[johnridesabike]

ReScript syntax, so types are non-recursive by default:

@gentype
type t = int

module M = {
  @gentype
  type t = array<t>
}

Outputs:

// tslint:disable-next-line:interface-over-type-literal
export type t = number;

// tslint:disable-next-line:interface-over-type-literal
export type M_t = M_t[]
