Adjust queries for operations that use only a transaction ID

[awrichar]

There are a few queries to GetOperations that attempt to load operation inputs only by looking at the operation type and the transaction ID. One example:

firefly/internal/events/tokens_transferred.go

Line 36 in 47ae1fd

fb.Eq("type", fftypes.OpTypeTokenTransfer),

Due to operation resubmission, transactions may now contain multiple operations of a given type, meaning that there is a potential source of confusion here in terms of which operation is loaded. It may not matter if all the operations have identical inputs (which is currently the case for retries) - but worth double-checking that this doesn't cause problems now or in the future.
