Add tests for the `block-tracker-inspector` middleware — which makes sure that the block tracker never has a reference to the latest block which is less than a block number that shows up in an RPC method's response — and the Infura middleware — which takes care of sending the request to Infura, and will retry the request up to 5 times if Infura sends back a certain type of error. Note that the `retry-on-empty` middleware is not tested because it currently has a [bug][1] which is making it ineffective. [1]: https://github.com/MetaMask/eth-json-rpc-middleware/issues/139
