Delete confirm-token-transaction-switch component

[jpuri]

Component confirm-token-transaction-switch takes care to get token relates data from using selectors and other hooks and rendering token routes passing this data. We need to do following refactor:

1. Minimise props passing from confirm-token-transaction-switch. This can be done by getting this data directly in confirm-approve and confirm-token-transaction-base components. Both of these are functional components. Only 1 prop transaction should be required to pass down to various components.

2. Move the 5 routes mapping to /pages/confirm-transaction.component.js

3. Add more unit test coverage here /pages/confirm-transaction.test.js for the 5 routes added to it

4. Delete /pages/confirm-token-transaction-switch.js
