Apicurio-studio: Environment Var "APICURIO_SHARE_FOR_EVERYONE" doesn't work good enough

Hi!
I was trying the environment var APICURIO_SHARE_FOR_EVERYONE.
I can see and edit API's from other users, but it's not working to see "Collaborators" or "Mocks".

Searching the cause, i found that the service "getMocks" doesn't check the property "isShareForEveryone()" and return a 404 HTTP Error Satus, becouse the user don't have permisions. Same for the "collaborators" section.

https://github.com/Apicurio/apicurio-studio/blob/master/front-end/studio/src/app/services/apis.service.ts

this.endpoint("/designs/:designId/mocks",

```

public getMocks(apiId: string, from?: number, to?: number): Promise console.info("[ApisService] Getting all mocks for API %s", apiId);

    let getMocksUrl: string = this.endpoint("/designs/:designId/mocks", {
        designId: apiId
    }, {
        start: from,
        end: to
    });

    let options: any = this.options({ "Accept": "application/json" });

    console.info("[ApisService] Fetching API mocks: %s", getMocksUrl);
    return this.httpGet<ApiMock[]>(getMocksUrl, options);
}

> this.endpoint("/designs/:designId/collaborators",

public getCollaborators(apiId: string): Promise console.info("[ApisService] Getting collaborators for API Design %s", apiId);

    let getCollaboratorsUrl: string = this.endpoint("/designs/:designId/collaborators", {
        designId: apiId
    });
    let options: any = this.options({ "Accept": "application/json" });

    console.info("[ApisService] Fetching collaborator list: %s", getCollaboratorsUrl);
    return this.httpGet<ApiCollaborator[]>(getCollaboratorsUrl, options);
}
