disable checks on "filtert" (default does not allow bookcal from other entities)
fix : add check on entites for bookcals

FIX bookcal : FIX : check on entities + not displaying calendar if multicompany ON

In multicompany context, we have to check on entities so only display shared agenda/bookcal AND have to disable checks on "filtert" (default only allow bookcal from same user, but is not altered by bookcal)

Module builder add more and more code with no sense !! getEntity($object->element) doesn't make sense, object is "availabilities" and "bookcal_availabilities" table has no entity field !!

@eldy ce n'est que mon opinion, mais un module fait avec Module Builder et qu'on veut intégrer a Dolibarr devrait être nettoyé, voir réécrit correctement !
