Add check connectable session before connect to mobile on `Keplr Mobile`

[HeesungB]

Overview

When connecting the Keplr Mobile wallet with Wallect Connect, I set it to connect to an existing session if one exists.

Reasons for the change

For examples, proceed to the example source in cosmos-kit.

1. The connection works fine when there are no sessions. ![first connect]()
2. However, if you refresh the page after connecting, it will request connect multiple times due to the source below in the packages/react-lite/src/hooks/useChain.ts file.

   // temporary solution for sync not working when the used chain is changed without page rendering (only component rendering)
   useEffect(() => {
   const currentWallet = window.localStorage.getItem(
     'cosmos-kit@2:core//current-wallet'
   );
   if (
     sync &&
     chainWalletContext &&
     chainWalletContext.isWalletDisconnected &&
     currentWallet
   ) {
     connect(currentWallet);
   }
   }, [chain, assetList]);

3. Ask the app to confirm the connection via wallect connect signClinet.connect.
4. You'll see multiple requests, as shown below. ![try to connect]()

What changed.

• Always create initKeplrWCClient after connecting via Keplr Mobile, instead of creating initKeplrWCClient with an existing session if one exists
• I've implemented session restore in our DApp in the documentation below https://docs.walletconnect.com/api/sign/dapp-usage#restoring-a-session
