Resolve failures in json and jsonb regression tests

The failures were caused by failed distribution key updates, which also
caused differences in subsequent query results. Instead of making the
table replicated as usual, I've decided to use DISTRIBUTE RANDOMLY in
this case, because we don't have that exercised in the tests yet.
