[FIX] base: groups also distribute branding

When there is a:

`groups="..."`

on a qweb view, when you edit the view with the editor then save all
groups will be removed since they are processed (so either we don't see
`groups` in the rendered view, or we don't see the element itself).

With this change, the "where should this part be saved when edited"
branding will be distributed to elements with `groups` attribute.

Added test without change failed with:

  AssertionError: {'data-oe-model': 'ir.ui.view', 'data-oe-id': '827',
                   'data-oe-field': 'arch'} != {}

because branding was added to `root` tag before change.
