Broken bundles after upgrade to 1.2.0

[darkalor]

After getting an update from 1.1.0 to 1.2.0 our babel bundle is not being transpiled correctly. Note that we're using babel 6.26.

Output with 1.1.0

/******/ ([
/* 0 */
/***/ (function(module, exports, __webpack_require__) {

    "use strict";

    var _isExtensible = __webpack_require__(1);

    var _isExtensible2 = _interopRequireDefault(_isExtensible);

    var _keys = __webpack_require__(2);

    var _keys2 = _interopRequireDefault(_keys);

    var _typeof2 = __webpack_require__(3);

    var _typeof3 = _interopRequireDefault(_typeof2);

    var _defineProperty = __webpack_require__(4);

    var _defineProperty2 = _interopRequireDefault(_defineProperty);

    var _create = __webpack_require__(5);

    var _create2 = _interopRequireDefault(_create);

    function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }

    var testsContext = __webpack_require__(6);

    var runnable = _get__("testsContext").keys();

    _get__("runnable").forEach(_get__("testsContext"));

Output with 1.2.0, note the import statements that were not transpiled

/************************************************************************/
/******/ ([
/* 0 */
/***/ (function(module, exports, __webpack_require__) {
    "use strict";

    import _Object$isExtensible from "babel-runtime/core-js/object/is-extensible";
    import _Object$keys from "babel-runtime/core-js/object/keys";
    import _typeof from "babel-runtime/helpers/typeof";
    import _Object$defineProperty from "babel-runtime/core-js/object/define-property";
    import _Object$create from "babel-runtime/core-js/object/create";

    var testsContext = __webpack_require__(1);

    var runnable = _get__("testsContext").keys();

    _get__("runnable").forEach(_get__("testsContext"));

Same. Babel 6.26, had to revert to rewire 1.1.0.
