Support mapping events for transactions with multiple operations

[stwiname]

Description

Up until now, we had not come across a case where a transaction had multiple operations and events emitted. There was an assertion so we would catch this case. Now that we have found a transaction we can correctly handle it.

We now also map the events to the operations correctly using the operationIndex that is not exposed via typescript types but exists on the object

Fixes #131
