Keeping tree intact when using onlyIncluded flag

[davearel]

The onlyIncluded flag seems to be ignoring the existing tree, which makes it impossible to include pod styles or anything that is dynamically created in the build process.

Using the existing tree allows me to include sass files that were dynamically created without losing the performance benefit of only compiling app/styles and explicitly defined node/bower modules.

This modifies the previous PR of #140, and fixes webark/ember-component-css#203

(Thanks to @webark for the proposed fix)

Nice one @davearel. Thanks!

I'm not using ember-component-css on any of my projects. I presume you've tested this manually?

[webark]

@aexmachina i tested it already, and worked great! thanks for this!

[simonexmachina]

Cool! Published v6.1.0.

[davearel]

Thanks @aexmachina and @webark!
