Bug 9126: Do not return from Check too early.

Bug 9126: Do not return from Check too early.

If there is no errors, it should continue instead of returning true.

+ move a block of code at the end of Check function. This avoid
detaching and re-attaching a HTML block if there are errors.

The following queries show us the issues:
select count(*) from items;
select * from aqorders_items where ordernumber=XX;

To test:

AcqCreateItem = receive
UniqueItemFields = barcode

1) Create a new basket
2) Create a new order with quantity > 1
3) Close the basket and create a new invoice/shipment
4) Receive only 1 item.
   - Fill out the first item form with item type only. Click add.
   - Don't change second item form at all.
   - Click save.

Before patch:
2 items are created on the record, both with the selected itemtype.

After patch:
Only 1 item is created, which is correct.
