contains different prices per quantity, the price is not changed
when computing quantity.
This PR fixes this.

Variable quantity in contract recurrent invoicing
=================================================
With this module, you will be able to define in recurring contracts some
lines with variable quantity according a provided formula.
Configuration
=============
* Go to Sales > Configuration > Contracts > Formulas (quantity).
* Define any formula based on Python code that stores at some moment a
float/integer value of the quantity to invoice in the variable 'result'.
You can use these variables to compute your formula:
* *env*: Environment variable for getting other models.
* *context*: Current context dictionary.
* *user*: Current user.
* *line*: Contract recurring invoice line that triggers this formula.
* *contract*: Contract whose line belongs to.
* *invoice*: Invoice (header) being created.
Usage
=====
To use this module, you need to:
* Go to Sales -> Contracts and select or create a new contract.
* Check *Generate recurring invoices automatically*.
* Add a new recurring invoicing line.
* Select "Variable quantity" in column "Qty. type".
* Select one of the possible formulas to use (previously created).
