[fix](transaction load) transaction may publish stuck if fe restart (#…

…44190)

1. a transaction for txn load is committed and not published
2. restart FE
3. the `subTxnIdToTxnId` in `DatabaseTransactionMgr` is empty, not
record the map of sub txn_id to txn_id
4. if BE report tablet and txn infos, FE will get transaction state to
judge if the txn load info in BE can be removed, but get txnId is null
from `subTxnIdToTxnId`, so be remove the txn load info
5. the publish will fail because `publish version failed on transaction,
tablet version not exists`
