Async syntax does not work

[bkostrowiecki]

I'm afraid that async syntax does not work properly:

Minimal test case:

# async-test.feature
Feature: Test async function

Scenario: Test async function
    Then Test async function

# async-test.steps.ts
import { binding, given, then, when} from 'cucumber-tsflow';

@binding()
export class AsyncFunctionSteps {
  @given(/Test async function/)
  public async givenAnAccountWithStartingBalance(amount: string) {
    await this.test();
  }

  private async test() {
    return new Promise((resolve) => resolve());
  }
}

The results:

Failures:

1) Scenario: Test async function # features\async-test.feature:3
   √ Before # node_modules\cucumber-tsflow\src\binding-decorator.ts:78
   × Then Test async function # node_modules\cucumber-tsflow\src\binding-decorator.ts:176
       Error: function uses multiple asynchronous interfaces: callback and promise
       to use the callback interface: do not return a promise
       to use the promise interface: remove the last argument to the function

I'm sorry, you can close this.

This is just misleading message when you declared more arguments in the function than you declared in the step decorator descriptor.
