fix(sdk): change insomnia.test mechanism to improve the nested test cases

[ihexxa]

Changes

• Change the mechanism of insomnia.test to improve the nested test cases
• Added smoke tests

Add sync or async cases in script to test it:

          insomnia.test('asyncHappyTestInFunc', () => {
            insomnia.expect(200).to.eql(200);
          });

          insomnia.test('asyncHappyTestInFunc', async () => {
            insomnia.expect(200).to.eql(200);
          });

Could there be any compatibility issues since the function passed to test() is executed asynchronously now?
