[trunk/7.0] uninstalling a module removes sql views, breaks reporting system

[PabloCM]

Version: 7.0 2013-11-04 nightly build 002515
Description:
Currently, when you uninstall a module that creates a db view (eg: sale_stock/report/sale_report.py) it removes the view. Since db view inheritance is non existent, those modules who add fields to an existent report (sale_stock does that) break the report when uninstalled.
How to reproduce:
1- Create an empty db
2- Install sale, install stock
3- Go to Settings->Configuration->Sales and uncheck "Trigger delivery orders automatically from sales orders". This will uninstall the module sale_stock
4- Go to Report->Sales->Sales Analysis and you will receive an error because the db view the report model is based on has been deleted from the db

Maybe it's a lack of a working report inheritance system more than a simple bug, but currently it is generating malfunction in a "release" version.
