Add menu entry "Reports" in sale / purchase / stock
When we extend a base module sale and purchase for example, we don't found Reports menu entry as Financial Module, the problem is when a not official module add Reports menu entry, and next you install sale opportunity for example, in the end you get two Menu entries Reports on Sale
Sales
|__ Configuration
|__ Sales
|__ Reports (By sale opportunity)
| |__ XXXXXX
| |__ XXXXXX
|
|__ Reports (By another no official module)
|__ AAAAAAA
The purpose is add menu entry by default "Reports" to official modules sale, purchase and stock, even if there is not default reports in this modules.
