Api method with optional parameter still generates client with mandatory parameter

[Fernando Minoru Baba]

Writting an api controller action like the following:

        [HttpGet("control")]
        [ProducesResponseType(typeof(Response<DataTransfer.ControlRegister.Control[]>), 200)]
        public async Task<IActionResult> ControlGetAll(bool includeParameters = false)
        {
            var rules = await this.policyService.GetAllControlsAsync(includeParameters);
            return this.Maybe<DataTransfer.ControlRegister.Control[]>(rules.Select(DataTransfer.ControlRegister.Control.From).ToArray());
        }

Should have the parameter includeParameters as optional, but the generated code still requires that parameter to get the correct response.
