fix: fetch discussion and ressources info when accepting a group invitation

Also ensure that the actor is included in PERSON_STATUS_GROUP, to stay consistent with LOGGED_USER_MEMBERSHIPS as used in MyGroups.vue.

The accept-invitation and refuse-invitation events needed to be emitted before refetching PERSON_STATUS_GROUP, so they can be caught by GroupView.vue before <InvitationsList> is destroyed due to the v-if becoming false.

Fixes #1800
