feat: redirect logged users to /home

[wa0x6e]

Summary

Closes: https://github.com/snapshot-labs/workflow/issues/158

This PR will redirect logged in users to /home when requesting for /

How to test

1. Go to /
2. It should show a loading indicator until it detect whether you're a guest or connected user
3. If you're not connected, it should show the landing page
4. If you're connected, it should redirect to /home

Note

This will always show the Loading icon until the log in is complete.

When you're logged in, but with metamask locked, it will show the loading indicator until you unlock metamask, or reject the unlock.

If metamask is locked

Is it expected? feels bit weird

[ChaituVR]

why we want to show a loader here 🤔

[wa0x6e]

To not flash the landing page.

Else, it will show the landing page, while we're connecting the user async

[ChaituVR]

We should have some localstorage variable (add value when user connects and delete if the user logout)
if user have this value, we should always redirect to /home , else show /

Then we wait for user wallet connection on /home, if user fails to connect his wallet, we should delete localstorage variable and redirect back to /

(also we should not try to auto-connect if user doesn't have this localstorage value, this may solve #478)

I think the issue is that we can not differentiate if the user is ready to be logged or if Metamask / user wallet is locked, this cause an issue where Metamask or WalletConnect will be triggered for login on first page load. Wagmi may fix that, or it could be with a change on Lock.

[bonustrack]

The ideal behavior would be similar than Uniswap (which is using Wagmi), where user dont get Metamask or their wallet triggered if it's locked, but still autoconnect if it's not locked

[wa0x6e]

This ideal behavior depends on some changes on lock side, and will be on another PR

tACK

Let's merge this when we can actually, it make much easier to test
