Remove test delays (#5579)

davimacedo · web-flow · commit 893f1d376e60 · 2019-05-14T11:34:51.000-07:00
* Changing __indexBuildCompletionCallbackForTests callback to serverStartComplete

* Improving serverStartComplete callback to avoid production unhandled promise rejection

* Add test to check inexistence of unhandled promise rejection on server fail

* Removing some hooks delays

* Removing delay after reconfigureServer

* Improving code style
