Investigate Set component allocations with Ledger

[rootulp]

I'm having trouble getting the set allocations to show up when connecting my ledger.
The error I'm receiving is An operation that changes the device state is in progress.

I'm not an expert on our ledger integration. This shows up in my google search:

Investigate this on website-v2-master branch

This looks caused by https://github.com/SetProtocol/index-ui/blob/46e42c0122b02948a8a7ce1de1b5d8186caa49a8/src/utils/setjsApi.ts#L70

index-ui doesn't do proper error handling so we should add a .catch() to the function that invokes this method. set.js may also need to be updated to catch the error and propagate a stacktrace.

Ledger wallet appears problematic for all providers that make requests to set.js (StreamingFeeProvider, TokenSupplyProvider, and SetComponentsProvider).
