Fix running the tests with sync 3.14
Fix running the tests with sync 3.14

3.14 added a new property to the __ResultSets table and a few of the tests use
an object schema read from the table, so object creation in those tests now
require a value for that property. Supplying a value for a property that
doesn't exist is harmless, so there's no need to make this conditional.
