Ava throws `Cannot read property 'moduleName' of null` since `0.19.0`

Description

Upgrading ava from 0.18.2 to 0.19.0 broke the tests in ws-promise. Running ava will cause Cannot read property 'moduleName' of null.

This still happens in 0.19.1.

Test Source

No tests are required to reproduce; commenting out all tests in ws-promise results in the same error.

Sorry, it somehow hadn’t clicked that you were using AVA to develop ws-promise, I thought it was a dependency!

This is due to a bug in the module we started using in 0.19 to resolve Babel options: https://github.com/novemberborn/hullabaloo-config-manager/issues/10

For now you can work around this by not putting ["transform-runtime"] in an array, or by specifying an empty options object (["transform-runtime", {}]). I’ll try and get a fix out soon.

hullabaloo-config-manager@1.0.1 is now available.
