Description

When running the sample of [ti.worker](https://github.com/appcelerator-modules/ti.worker/tree/master/ios/example) it works fine. As soon as "terminate" is clicked the app crashes. This is both on classic and Alloy apps. It blocks the customer from implementing a heavy feature (where async is needed) Crash log:

This is covered in [this PR](https://github.com/appcelerator-modules/ti.worker/pull/15) already. A new module version is attached for testing.

App is not crashing with 1.2.0 and sample works & runs 3 workers as expected. Tested using 7.1.0.GA on iOS 11.2 where it previously crashed.
