Apply TransactionBatch at end of top ->Atomic call

[elacour]

8862bd94d introduced a regression, seen at least when calling Ticket/Display.html?id=X&Action=YYY&Status=ZZZ. TransactionBatch scrips are triggered for Owner change (Take here) but not for Status change.

All changes are wrapped inside an Atomic call. Action args is processed first and trigger a $TicketObj->Take which calls ->SetOwner. This last one wrap itself inside another Atomic call.

In ->Atomic, the first commited transaction trigger application of TransactionBatch which itself forbid further execution through ->RanTransactionBatch flag.

This commit apply TransactionBatch only after end of all transactions.

It is also executed after txn commit to be consistent for all transactions such as nested ones (which was old behaviour).
