bug: TypeError: Cannot use 'in' operator to search for 'PriceFeedRemoved' in undefined

[FairyFromAlfeya]

Description: traceTree.findEventsForContract() seems to be broken

Inside viewTracingTree.ts:

findForContract = ({ contract, name, }) => {
  //@ts-ignore
  if (name in contract._functions) {
    return this.findByType({ name, type: types_1.TraceType.FUNCTION_CALL, contract });
  }
  return this.findByType({ name, type: types_1.TraceType.EVENT, contract });
};

contract._functions is undefined
