* Fix retrieving BadgeAssertion data from Badgr
With edx#27181, the integration with Badgr was updated and fixed to
be working with the Badgr v2 API. However, retrieving the Badge Assertion
data from Badgr still needs to be updated for the new json response
structure so we can save it at our end as well.
