"import * as ... from ..." syntax breaks when upgrading from ember-auto-import 2.6.3 to 2.7.2

I am not sure if this is necessarily an ember-auto-import issue or a issue in one of ember-auto-import's dependencies (babel, or rollup or webpack?) but this surfaced when upgrading ember-auto-import from 2.6.3 to 2.7.2.

In our app we had a handful of files that were using import * as moment from 'moment-timezone' style imports to import CJS packages. I don't think we had a good reason to use this style import over a simpler import moment from 'moment-timezone', syntax, but none-the-less these worked fine with ember-auto-import 2.6.3 and earlier.

When we upgrade ember-auto-import to 2.7.2 these imports started breaking and we would see errors such as TypeError: moment is not a function

The easy solution was just to update the import syntax to no longer use import * as ... but I am curious to understand what caused these to break.
