Fix WalletConnect GameObject runtime error.

[jeffgamedev]

Fix game object attempting to start coroutine when game object is not active in hierarchy.

After connecting to a wallet with WalletConnect, if the application loses focus, and then resumes focus, WalletConnect attempts to start a coroutine to generate a QR code, however the UI is not active and the start coroutine call fails in a runtime error. This change checks if the game object is active before starting the coroutine.

I've tested that WalletConnect is able to properly connect to a wallet after logging out of a wallet and using again.

I think this might break mobile behavior, async is not so fun in the editor but might be needed on such platforms, have you tested on Android?

I have not tested on Android, only in editor.

We're in the process of updating WalletConnect to V2 so will merge this for now since QR is not going to be shown on mobile in most cases, ty ser
