4.0.0 Dependency bundled as two separate instances in production build

[draoncc]

Minimal example project: https://github.com/draoncc/FuseBox-GraphQL-Apollo-CoreSchema-issue-example

Run yarn build, followed by node dist/app.js. It should print a GraphQLErrorExt. The issue is that only one instance of "graphql" may be bundled, but when inspecting dist/app.js, graphql seems to be imported twice:

L32  var graphql_1 = __fusereq(3);
L107 var graphql_mjs_1 = __fusereq(11);

The only solution seems to be to add "graphql" to the list of ignored dependencies in FuseBox' configuration, and installing it separately.

How come graphql is imported as two separate instances instead of one, and is this preventable?
