analytics: error importing in Meteor 1.5 - Path must be a string. Received undefined

Hi, importing of okgrow:analytics , @okgrow/auto-analytics is broken in Meteor 1.5.

After upgrading to Meteor 1.5 I get:

<...>/.meteor/packages/coffeescript/.1.12.3_1.yrisuj++os+web.browser+web.cordova/plugin.compileCoffeescript.os/npm/node_modules/meteor/promise/node_modules/meteor-promise/promise_server.js:190
      throw error;
      ^

Debugging the ImportScanner (/tools/isobuild/import-scanner.js:617), reveals that the two variables in the ImportScanner.prototype._getRelativeImportId have values as follows:

parentPath = node_modules/meteor/okgrow:analytics/node_modules/@okgrow/auto-analytics/vendor/analytics.min.js
childPath = undefined

removing okgrow:analytics from the project fixes the problem.

I don’t know enough about es6 imports and the recent changes to meteor/babel to know why this is happening…

But I think it’s a good start for investigation. Or maybe I am doing something horribly wrong? Possibly this is an issue for the meteor team…

For the sake of completeness.
