fix: resolve issue with connecting to solana namespace

[RyukTheCoder]

Summary

Resolved an issue in the Phantom wallet related to connecting to the Solana namespace. Previously, after disconnecting the wallet and attempting to reconnect to both Solana and EVM namespaces, errors occurred with the Solana instance. This problem was fixed by modifying the connection process to the Solana namespace, ensuring that account requests are not sent if the public key is already available.

How did you test this change?

Connected to Solana namespace, then disconnected and then connected to both namespaces. Observed that both namespaces get connected without any error.
