Shouldn't we still check this?

It wasn't needed because we did not create connections earlier.
Now that we create connections, add the check back. 

-  EXPECT_FALSE(turn_port_->connected());
+  EXPECT_TRUE_WAIT(!turn_port_->connected(), kTimeout);
 }
 
 // Test that CreateConnection will return null if port becomes disconnected.
