Prevent dbVersion refreshes from failing transactions in txn_recover_decision_using_recovery_router.js

txn_recover_decision_using_recovery_router.js runs transactions without transient error retry logic. If a database version refresh is triggered concurrently with a transaction, the transaction can reach the 5ms lock timeout waiting for an IX database lock and fail with a transient error. The test should be modified to not fail because of this, either by adding retry logic or forcing shards to refresh their database version earlier when no transactions are running.
