Hofix: error sum of weights in root subnet if any subnet does not exist
Describe the bug
If the subnet does not exist, then the sum of the weights in the network root is not calculated, but raises an error.
To Reproduce
With bittensor version 6.12 run the code:
import bittensor as bt
sub = bt.subtensor()
meta = sub.metagraph(netuid=0, lite=False)
Expected behavior
This raises error:

│ 763 │ │ │ │ │ │ n_subnets, list(uids), list(values), subnets │
