transaction: only delete journal on successful abort/commit

This solves that the journal file was always deleted when the transaction
was deleted, no matter whether the abort (rollback) succeeded or not.
Thus, never supporting a hg recover. The journal file is now only deleted
on close (commit) or a successful abort.
