Solved when i got back to djangoldp==0.6.17

Any idea why this occurs and how to solve..? Is djangodlp 0.6.17 needed to run V0.9 ?

Also, found this ticket referrencing the same issue startinblox/djangoldp-packages/djangoldp#101 (closed)

Checked if the solution mentioned in the related commit (startinblox/djangoldp-packages/djangoldp@90f8e5a0) was implemented, and it is..
