The ":ID" doesn't be replaced by the transaction ID

Version: 1.7.*

After creating a new transaction and reserving an item, I found the column "reason" in the table "inventory_stock_movements" had a problem.

That is, the ":ID" doesn't be replaced by the transaction ID.

The column "reason" just displays like "Reservation occurred on Transaction ID: on 2016-05-20 20:58:27"

$item  = Inventory::find(13);
$stock = $item->getStockFromLocation($location);
$transaction = $stock->newTransaction();
$transaction->reserved(5);

Thank you for your masterpiece!!
