[FIX] sale_timesheet: expense reinvoiced at cost in plan project

When reinvoice an expensable product at cost, it should
takes the amount on the analytic lines created when posting
expenses, instead of the cost on the product.
For instance, you create an expense with the generic expense
product (for a lunch, for instance). The cost of the generic
product is zero, but you don't want to see that amount in
your project plan, and we don't want to create a product
per "lunch expense".
