[6.1] exception from report not shown

Hello,

Some error aren't displayed in web client but are shown in GTK client.

Here is how to reproduce:

- Install a new DB with demo data.
- Install package eInvoicing & Payments
- Go in accounting -> Customer Invoice
--> Open Agrolait's invoice
- Try to print the report BVR Invoice

Result it does nothing... It must show the error to the user.
In server trace I can read :

Fault: <Fault warning -- UserError

No bank specified on invoice:

In GTK client everything is fine as an error is corectly poped

It is needed to show to the web user the error that is raised.

Regards,
Yannick
