SERVER-66618 Wait in test for resharding coordinator to persist abort.

Fixes an issue in the resharding_coordinator_recovers_abort_decision.js
test where the reshardingPauseCoordinatorBeforeBlockingWrites failpoint
is being released too early and allowing the resharding coordinator to
decide to commit the resharding operation instead.
