[IMP] web: save a has_group rpc at webclient startup

...when voip addon is installed.

We want to avoid predictable rpcs that are systematically done at
webclient startup. In particular, the voip service needs to know if
the user has group "base.group_user", which produces a rpc when
the service is started.

To avoid this, this commit adds the information in the page
directly. As this information is also useful at other places
(even though it's not at startup), we directly add it to the
groupCache of the user service (and we do the same for the
"base.group_system" group, which we also receive in the page).
