Bug 18723: Change dot into comma

Bug 18723: Change dot into comma

This fixes the regression that multiplies the amount entered by 100
when CurrencyFormat is set to FR. It replaces the last dot with a
comma before dealing with the value of ActualCost and ReplacementCost.

Test Plan:
a)Replicate the issue:
    0- Set CurrencyFormat to FR
    1- Go to Acquisitions
    2- Search for a Vendor
    3- Click on "New basket"
    4- Give basket a name and click "Save"
    5- Click on "Add to basket"
    6- Add an order through preferred method
    7- In Accounting details, enter a vendor price with dot decimal (i.e. 19.44)
    8- Save your order line
    9- Click on "Close this basket"
    10- Confirm closing of basket by clicking on "Yes, close"
    11- Click on "Receive shipment"
    12- Enter an invoice number and click "Next"
    13- Click on "Receive" to the right of your order
    14- In Accounting details, notice the Actual cost is written with a decimal dot.
    15- Change the Actual cost, using a dot decimal (i.e 20.99)
    16- Receive the order
    17- Click on "Save"
    18- In "Already received" notice the price is multiplied by 100 (i.e. 2099,00)
    19- Click on "Cancel receipt"
    20- Click on "Receive" to the right of your order
    21- In Accounting details, change the Actual cost, using a comma decimal (i.e. 20,99)
    22- Receive the order
    23- Click on "Save"
    24- In "Already received", notice the price is correct.
b)Apply the patch
c)Test the patch:
    1- Click on "Cancel receipt"
    2- Click on "Receive to the right of your order
    3- Change the Actual cost/Replacement cost, using a dot decimal (21.99)
    4- Receive the order
    5- Click on "Save"

    7- Change the Actual cost, using a comma decimal (21,99)
    8- Click on "Save"
    9- In "Already received", notice the price is still correct.
