steps to reduce:

1. choose Symbols
2. enter Add/remove your symbol page, choose Add new
3. change to Enter new symbol page, enter any number or character of certain stock
4. choose the right stock and click enter

Actual Result:
go back directly to Add/remove symbol page, new symbol will be added in the list

Expected Result:
click enter, the latest status will be shown on the page of Enter new symbol to verify it's the right symbol we'd like to add to symbol list,
then go back to Add/remove symbol page

In twse-cli - migration.js, the notifiers would be undefined when notifier not exist and lead to Object.entries(notifiers) throw exception.

const { notifier = {}, notifier: { notifiers } = {} } = state;

Error Log

  var newNotifiers = Object.entries(notifiers).reduce(function (acc, _ref) {
                            ^

Step to reproduce:

1. choose Symbols
2. change to Add/remove you symbols page, choose Add new
3. change to Enter new symbol page

Actual Result:
There is no way back to previous Add/remove Symbols page in Enter new symbol page.
If user does not want to add any symbol at this time, then the only way to exit is to close this problem to restart.

Expect Result:
Add some ways (e.g. enter exit string) to go back to Add/remove Symbols page
