[FIX] odoo: copy_translation translates the wrong view

With website_version, when publishing a version and copying the current version,
the copy_translation wrote a new translation for the copy of master in the published
view instead of the copied view.

Reason:

When writing in the view, odoo checked in the context the current version and
wrote in the view corresponding to the key and the verion seen in the website.
So when copying a view, it translated the copied view instead of the copy of
the view.

The write is made by the function copy_translation with the line:

   "new_wo_lang[name] = old_wo_lang[name]"
