Subject: [PATCH] add a jest for `SwitchToHistoryLink` that tests current
 history case

For the current history, we show a title saying "This is your current history", therefore, a mock is added here for `historyStore.currentHistoryId` to always return `current-history-id` regardless of which history you mount. This is done so that we can test the case when the history is current, and not.
