Add switch account feature for Expo, Elecetron, and React Web

[by12380]

Currently the login button will directly log user in with the first account that the user has used to log in on the first time (despite having logout and login again). Will need to create a separate button that allows switching account.

Details:

• Create a 'Switch account' button placed in the Profile page.
• Create redux action and reducer for 'switch account' functionality. (Copy and reuse the login action creators in its respective project and simply append prompt=login as a parameter in the login settings/options.

Completed the above feature for:

• React Web
• Electron
• Expo
