[BUG][typescript-node] Missing type argument when using oneOf, $ref & Array

Description

When using oneOf with $ref and the content of $ref is an array, the generator ignores the type of the array which leads to the typescript error:
Error:(20, 20) TS2314: Generic type 'Array<T>' requires 1 type argument(s).

export class Schema1MyData {
    'data'?: any | Array;    // this should be Array<string>!
//...

Command line used for generation

--generator-name=typescript-node

Reproduce the issue with the supplied OpenAPI 3.0.1 declaration and --generator-name=typescript-node, checking the generated type for Schema1MyData.data. No source file or test is named in the report, so trace the typescript-node generator from that reproduction. Done means the generated property uses the referenced array element type, such as Array, without the TypeScript generic-argument error.
