[FIX] website_crm_score: avoid traceback when domain filter cannot evaluate the tem_user domain.

Now, we manage more case:
    Domain with tuple like [('country_id', '=', 'Belgium')]
    Domain with Boolean Value like [('country_id', '=', False)]
    If domain cannot be evaluate we display error in the filter
