Package version

4.1.0

Node.js and npm version

Node - 11.14.0
NPM - 6.9.0

Sample Code (to reproduce the issue)

These work:-

test('test name', async (ctx) => {
  // This works
}).timeout(100)

test('test name', async (ctx) => {
  // This works
}).retry(3)

---

However, these do not:-

test('test name', async (ctx) => {
 // This doesn't work
}).timeout(100).retry(3)

test('test name', async (ctx) => {
 // This doesn't work
}).retry(3).timeout(100)

It produces this error:-

TypeError: Cannot read property 'retry' of undefined
