Using manageState will fail in cronJob when the extension is locked

[Montoya]

This section of code from /snap/index.tsx:

export const onCronjob: OnCronjobHandler = async ({ request }) => {
  const wallet = await Wallet.getCurrentWallet();
  const mainnet_client = new Client("mainnet");
  const engine = new NotificationEngine(mainnet_client, wallet);
  switch (request.method) {
    case 'NotificationEngine':{
      console.log("notification check");
      await engine.checkForNotifications();
      return null;
    }
    default:
      throw new Error('Method not found.');
  }
};

Access encrypted state inside of a cronJob handler. If the extension is locked, then the extension will pop up a window for the user to unlock the extension. This is annoying because it will happen every time the cronJob fires. There are two solutions:

• Never access encrypted state inside of a cronjob. If you need to access state, set the encrypted parameter to false, but you should not store anything critical in that state: https://docs.metamask.io/snaps/reference/snaps-api/#snap_managestate
• Check if the extension is locked from inside the cronjob. If it is locked, just return and do nothing. See how to check here: https://docs.metamask.io/snaps/reference/snaps-api/#snap_getclientstatus
