run_service.sh fails when the RPC is out of calls

[dvilelaf]

After updating to 7.0, I gor an out of RPC calls error:
requests.exceptions.HTTPError: 402 Client Error: Payment Required for url: https://gno.getblock.io/24bceb6e-8fc2-4fde-ad59-73322833d7f0/mainnet/

I then swapped my RPC and re-ran the script:

------------------------------
Updating on-chain service 97
------------------------------

PLEASE, DO NOT INTERRUPT THIS PROCESS.

Cancelling the on-chain service update prematurely could lead to an inconsistent state of the Safe or the on-chain service state, which may require manual intervention to resolve.

The issue commented here has been addressed already in PR #78 (Namely, the service Safe is not attempted to be swapped if it is in the correct state, i.e., if the Service Owner is already the Safe Owner)
