[FIX] base: debug assets in multi-website/multi-company

Before this commit, the assets were not found when the user is connected
in mode debug assets in a multi-website and multi-company. This occurs
because the attachments (assets) were created with the number of the
first website accessed, and cannot be loaded when trying to access the
second website.

The website_id is added in the creation of the views see:
09287027

Now, the attachments are created without the website number and is
shared between all the websites.
