 * Given an array of tabs, renders non linked bootstrap tabs.
 * When a tab is clicked it will trigger an event and provide the clicked scope.
 *
 * This component is used in apps that handle the API call.
 * If you only need to change the URL this component should not be used.
 *
 * @example
 * <navigation-tabs
 *   :tabs="[
 *   {
 *      name: String,
 *      scope: String,
 *      count: Number || Undefined || Null,
 *      isActive: Boolean,
