slapos_jio: fix ERP5Site_activeLogin

The commit dee343f3 said:
slapos_jio: after activate the login come back to WebSite and not to the portal.
    
But it actually went to the WebSection and not the WebSite.
    
This fixes ERP5Site_activeLogin on slapos master because right now we
have this URL in emails sent to customer to activate their login:
    
https://slapos.vifib.com/hateoas/connection/ERP5Site_activeLogin?key=XXX
    
So the script is setupping the came from as:
    
https://slapos.vifib.com/hateoas/connection/#!login?p.page=slapos{&n.me}
    
which is not working (returns AttributeError: form_view error)
    
The URL https://slapos.vifib.com/#!login?p.page=slapos{&n.me} is working
though.
