[FIX] web: pivot view nocontenthelp message

Since the commit https://github.com/odoo/odoo/commit/46cf65d68e9c13193dff4b563b9b0bbb2199dfc1
when help is not defined in action then nocontenthelp is displayed as
[object, object] due to the desciption passed from renderder of the
pivot view.

So in this commit while calling the NoContentHelper pass the
descitption as string instead of jquery element.
we can use the t-value in template but that string will create
issue for transalation so pass the desctiption from the pivot render.
