**Steps to reproduce:**
- Install Accounting and l10n_ke_edi_tremol
- Switch to a Kenyan company (e.g. KE Company)
- Configure USD currency:
  * Rounding Factor: 0.000100
  * Decimal Places: 4
  * Rate: 0.007729205731 Unit per KES 129.379400000000 KES per Unit
- Create a product with decimal in the price (e.g. 1234.56)
- Create an invoice:
  * Customer: [a Kenyan customer]
  * Currency: USD
  * Product: [the created product]
  * Taxes: 16%
- Confirm the invoice
- Send the invoice to fiscal device (It will not be possible without some credentials. However, if a breakpoint is set at the last line ("return" line) of "_l10n_ke_cu_lines_messages" method, the total amount in KSh sent to the fiscal device can be checked.)

**Issue:**
The total amount in KSh sent to the fiscal device is different than the total amount in USD converted to KSh with the used currency rate.

**Cause:**
In the "_l10n_ke_cu_lines_messages" method (the method used to compute the amounts sent to the fiscal device), a rounding is done by forcing the number of decimal to 2 without taking into account the configuration of the currency when computing the price.

**Steps to reproduce:**
- Install Accounting and l10n_sa_edi
- Switch to a Saudi Arabian company (e.g. SA Company)
- Duplicate "Customer Invoices" journal:
  * Default Income Account: 500001 Sales Account
  * Electronic invoicing: [disabled]
- Create a retention tax:
  * Name: Retention 10%
  * Amount: -10.00000%
  * Is Retention: [checked]

- Create an invoice:
  * Customer: [a Saudi Arabian contact] (e.g. ARAMCO Medinah Branch)
  * Journal: Customer Invoices
  * Invoice Lines:
    - Price: 100.00
    - Taxes: "Sales Tax 15%" + "Retention 10%"
- Confirm the invoice
- Print the invoice
- Scan the QR code on the invoice with an app like "E-invoice QR Reader"

=> In the QR code, the total amount of the invoice with VAT included is 115.00 and the total amount of the VAT is 15.00.
The amount of the retention tax is excluded from the total and the VAT amounts, which is the expected behavior.

- Create the exact same invoice with the duplicated journal without electronic invoicing
- Confirm the invoice
- Print the invoice
- Scan the QR code on the invoice

**Issue:**
In the QR code, the amount of the retention (-10.00) is taken into account.
The total amount of the invoice with VAT included is 105.00 and the total amount of the VAT is 5.00.
The QR code should provide the same amounts either the used journal has "Electronic invoicing" enabled or not.

**Cause:**
Depending on the presence of an electronic invoice document or not, the QR code is generated by the overriding compute method from "l10_sa_edi" or the original one in "l10n_sa".
However, the "Is Retention" field of the "account.tax" model is introduced by "l10n_sa_edi" module and when the QR code is computed by the original method, this field is not taken into account and the corresponding retention tax is wrongly handled like any other tax.

**Solution:**
Use the same total amounts than the ones computed in "l10n_sa_edi" (where retention tax are excluded) in the original compute method if "l10n_sa_edi" is installed.
