This is tough. The problem with a test like this is that you can't 
really tell that the sync is working as intended. It's possible that the 
ovn-nbctl is not actually waiting, but by coincidence, the database has 
its values updated before you check them.

You'd need something internal to ovn-nbctl to let you know that the 
database value has been updated prior to exiting to know for sure that 
the sync is working as intended.

How about we switch from 'get' to 'wait-until'? Let me try that.
