[BUG] [typescript-axios] parameter with date format has incorrect types

Description

If a date format is specified for a parameter, the generated code for axios will include the following:

      if (fromDate !== undefined) {
        localVarQueryParameter['fromDate'] =
          (fromDate as any) instanceof Date
            ? (fromDate as any).toISOString().substr(0, 10)
            : fromDate;
      }

However, the type for that argument in the generated method is fromDate?: string, which prevent us from actually passing a Date instance.

Either we remove that code, or change the type definition to be fromDate?: string | Date

sameproblem for typescript-rxjs. walkaround: change fromDate.toISOString() to new Date(fromDate).toISOString()

@rainmanhhh without a proper deserializer this thing won’t ever work. I’m in the last throes of testing my changes before submitting them back. The model generate and de/serializer will work now without the api libraries, so it will be able to be used with whatever transport you use.
