Resetting the app to a first run state

This is useful for testing the first run experience.

To re-see the first run screens you need to:

1. Run window.localStorage.clear() in the browser console (press ctrl-shift-I/cmd-shift-i to open, then type in console tab)
2. Delete the LBRY auth token in your OS keyring (https://lbry.io/faq/how-to-change-email)
3. Run LBRY

Note1: It will reset your auth token, so it's recommended on test installs. Otherwise, if your token is authorized for something like user reward approvals, it will need to be re-added.

Note2: You'll likely also want to move your wallet file, as some of the screens are dependent on a balance of 0.
