Issue being used as a nested addon

I encountered this issue trying to upgrade ember-light-table and noticed this problem.

    if (!process.env.EMBER_CLI_FASTBOOT) {
      app.import('vendor/element-resize-detector/element-resize-detector.js');
    }

Able to reproduce with ember 2.6 and a new addon project.

This issue seems directly related to this discussion about nested addons: ember-cli/ember-cli#3718

Moving ember-light-table to a peerDependency seemed to resolve this issue... so I'm moving on.

@nmcclay I have the same issue but I'm contributing for this addon. I cannot add ember-light-table as peerDependency. Is there a solution?
