Check that block node activation and inactivation works with a block
26ba25
graph that is built with individually created nodes.
26ba25
26ba25
RHEL: Disabled query-migrate call on the destination; this returns only
26ba25
an empty object in 2.12. Changed reference output for Python 2 (we lack
26ba25
the compatibility patches from upstream that make the output independent
26ba25
from the Python version).
