Rearrange GDD tests to cut down runtime.
Rearrange GDD tests to cut down runtime.

prepare-for-local tests resets the gp_global_deadlock_detector_period
guc to default 2mins time. Due to it any GDD test after that will take
atleast 2mins. Instead flip the order.

Ideally prepare-for-local test don't need to reset the guc. Instead
can use fault injector in local-deadlock-03 to avoid GDD from
kicking-in, but that's for separate commit.

This shaves off 6mins of isolation2 test time on my laptop.
