Getting backpack working with Ava #128

Any advice on how to get around this?

Error

Seems to stem from Babel 6 (Backpack) & Babel 7 (Ava) incompatibility

Module build failed: Error: Plugin/Preset files are not allowed to export objects, only functions. In /...path.../node_modules/backpack-core/babel.js

Backpack Core versions tried

^0.7.0
^0.8.0-0

Config

.babelrc

{
  "presets": [
    "backpack-core/babel",
    "@ava/stage-4",
    "@ava/transform-test-files"
  ]
}

Looking for a hack-through

As suggested here, tried to see if forcing babel-preset-back from version 0.5.0 to 0.8.0-0 would resolve the issue. But still receiving the issue.
