Fix scaffold issue #207

[mvdkleijn]

This fixes issue #207 for me, although the actual default feature test appears to not work. Not sure why, having no experience with it.

Please note Aruba version 0.8.1 is apparently not required as opposed to what is mentioned in #207 by @louisrousseau. Gem minitest was also not required.

Tested locally against Ruby 2.1.3 with the following gems:
