cubicweb #2186288 tabs use rql parameters while eid could be given [validation pending]

as the underlying ajax call support the eid param, we should use that rather than rql=rql_for_eid() for several reason :

  • when possible, we should not use the 'rql' url parameter so we can easily forbid when desired that at some point (hummm...)
  • giving eid rather than specific rql works nicer with caching and all.
