GroupId

[daviesd]

Some changes were made to GroupId between 2.5-beta1 and 2.5-beta2 that are
affecting me.

GroupId.Type changed from this

   all, friends, self, deleted, groupId;

To this

   objectId(0), self(1), friends(2), all(3);

We had extended AppDataService to support a groupId of @institution
(something that is relevant in our domain)

            osapi.appdata.get({
                userId: '@me',
                groupId : '@institution',
                appId : '@app'} )

However, I have concerns as to how this will work now, because I¹m fighting
through a unit test that does this

    groupId = GroupId.fromJson("@institution")

And it¹s throwing a IllegalArgumentException.

Can some one point me in the right direction as to how I¹m suppose to handle
something like this?

Thanks,
