Missing order by on nextNotLeased in stateful entity store (SQL)

[wolf4ood]

Bug Report

Describe the Bug

Implementations of SQL variant StateEntityStore for the nextNotLeased method miss the order by
when looking for the next items to process. This could lead to starvation for some state and it could
prevent some optimization (index creation) when fetching the items to process.

Observed Behavior

For example putting an index like this

CREATE INDEX IF NOT EXISTS transfer_process_state
    ON edc_transfer_process (state);

Makes the NextNotLeased.avoidsStarvation on TransferProcessStoreTestBase fails

Possible Implementation

add order by state_time_stamp on QuerySpec in all nextNotLeased SQL implementation
