[Python] Transaction is_open method throws an exception if called after transaction is committed

[james-whiteside]

Description

If the is_open method of a TypeDBTransaction is called after the transaction is committed, an exception is thrown instead of returning False. This is not the case if the transaction is instead closed, after which is_open functions as expected.

Environment

1. TypeDB distribution: Core
2. TypeDB version: 2.27.0
3. Environment: MacOS

Reproducible Steps

with TypeDB.core_driver("localhost:1729") as driver:
    with driver.session("test", SessionType.DATA) as session:
        with session.transaction(TransactionType.WRITE) as transaction:
            print(f"Deleting existing data.")
            transaction.query.delete(query="match $x isa $t; delete $x isa $t;").resolve()
            transaction.commit()
            print(transaction.is_open())
