Considering a block where there's only one occurence of this event, `graph-node` would duplicate it and call `handleTransfer` twice. Now this is fixed and it will be called only once per event/call that happened on chain.

   In the case you're indexing one of the impacted subgraphs, you should first upgrade the `graph-node` version, then rewind the affected subgraphs to the smallest `startBlock` of their subgraph manifest. To achieve that the `graphman rewind` CLI command can be used.
