[IMP] Report: handling of ir.values similar to the server actions one

When creating an ir.actions.report.xml record from the backend, ir.values allowing to display a report in the contextual more menu are not created. Added a button to force the creation.
we need the superuser_id as there is a rule over ir_values with the domain
[('key','=','default'),('user_id','=',user.id)]

i'm not sure what's the best group to reduce usage of these methods so i used
group_no_one (note: without group_no_one, it's impossible to reach the menuitems,
so it will only reduce in the scope of rpc calls). Done for ir.actions.server too
