Code Issues Proposed changes

test: add workaround for non-deterministic ovo object comparison 

The ComparableVersionedObject impl of the __eq__ method incorrectly
checks the list of changed fields in an object. The ordering of
this list depends on the python hash seed, which causes the test
to randomly fail. Reset the list of changes as a workaround until
the ovo bug is fixed.

# The __eq__ function works by using obj_to_primitive()

# occassionally the ordering of the list of changes
# varies, causing bogus equality failures. This is
# arguably a bug in oslo.versionedobjects since the
# set of changes fields should not affect equality
