Enable Autofill PrefillFormAndFill with execution order swap

Test PrefillFormAndFill often fails on some Mac versions (10.11, 10.13)
This CL attempts to fix by moving CreateTestProfile to before the
NavigateUrl step. All other tests have this order, and it could
perhaps help with execution without flake
