[transaction] handle ``mode`` default value in Transaction
The transaction mode is now explicitly passed at creation time and always read
from the Transaction object.
Note that there is a slight behavior change. The transaction mode is now set at
the creation of the transaction. Changes made to the default value have no
longer any effect on existing transaction.
