cy.task('coverageReport') timed out after waiting `180000ms`.

**Logs and screenshots**
Hi,

For some reason, with when i run cypress with the coverage flag, I'm getting the error:

```
CypressError: `cy.task('coverageReport')` timed out after waiting `180000ms`.

Because this error occurred during a 'after all' hook we are skipping all of the remaining tests.
```

Is there anything we can do to increase the timeout or there's something which i am missing?

My issue is similar to this issue: https://github.com/cypress-io/code-coverage/issues/134
