Use StableObjectJsonFixture from o.vo

StableObjectJsonFixture has been in o.vo since the 1.9.0
release and we require >=1.13.0 in g-r now, so we should
use the fixture from the library rather than keep a
duplicate in nova.

This is also needed to use o.vo 1.17.0 which has change
39a057becc10d1cfb5a5d5024bfcbbe6db1b56be that breaks the
fixture's erroneous unit test.
