TF-3396 Fix mobile app can not get the latest email when open app from terminated

[dab246]

Issue

#3396

Root cause

• Since we skipped get change when switching between mailboxes, we didn't get the latest changes when the app was in terminated state.

Solution

• To solve this problem, we perform get change emails the first time we open the app. This solution is useful when we disable Websocket or FCM and always receive the latest changes when opening the app.

Resolved

• Mobile:

• Web:
