[FIX] account : correct button title invoice email manually

Sending invoice in emails to customers now display View Journal Entry in
v16.2 instead of view Invoice.
Steps to reproduce the error :
1- Install accounting
2- Go to accounting/customers/invoices
3- Create an invoice and send it by email to the customer
4- View The email on mailhog

The reason of the error was becayse we didn't provide model_descirption
to the function of sending the email, so it will take the one by default
whch is Journal Entry.
