concatenatedProperties works in 1.13.6 but not obliged in 1.13.7+

The issue can be seen here:

Toggle the emberjs version string to see when it starts to fail.

{{ x-foo bar="quux"}} when bar is set to ["baz"] in component and concatenatedProperties: ['bar']

• 1.13.6: bar equals ['baz', 'quux']
• 1.13.7 bar equals quux'
  • I'm not entirely certain if this is the correct behavior and I'm missing some documentation somewhere.

This was exposed when I began digging into yapplabs/ember-modal-dialog#71.

Ugh. @mixonic told me so.

@rwjblue I have time to help with this, but I don't really know where to begin.
