Fix incorrect beacon values multicall error handling

[Siegrift]

Here we re-throw an error that is not handled anywhere in the call chain. See image below:

Couple of things to change:

• We should not re-throw the error
• This check should be removed
• Provider name here is unused and should be removed
• I think we should handle the error here and return an empty array in case it happens.
• Here I anticipated that processBatch function will not throw. I think this holds true (when we fix the issue), but we should have some last resort boundary (wrap in go and log unexpected error) in this function .
• The message should have lowercase Updatable
