[validation] Check if @shortcut and @aliases are supported correctly... together

[l-trotta]

Here's SpanTermQuery, where value is both a shortcut and has an alias (yes it's correct):

/**
 * @shortcut_property value
 * @ext_doc_id query-dsl-span-term-query
 */
export class SpanTermQuery extends QueryBase {
  /** @aliases term */
  value: FieldValue
}

All flight recorder tests fail with this one, saying:

Type '{ _name: string; boost: number; value: string; }' is not assignable to type 'FieldValue | QueryDslSpanTermQuery | undefined'.

and

Property 'term' is missing in type '{ _name: string; boost: number; value: string; }' but required in type 'QueryDslSpanTermQuery'.

So it seems like the combination of shortcut and aliases breaks both
