[FIX] web: see selection didn't show selection

This fix gives the domain to the "See selection" view opened from a
FieldCharDomain.

In Odoo 8.0, this widget is available at two places:

- mass_mailing: Marketing > Mass Mailing | Mass Mailing > (any
  newsletter) > "See selection".

- gamification: Settings > Gamification Tools > Challenge > (any
  challenge) > "See selection".

With this fix the "Selected records" view display selected records.
