Load purchase state from chain (#283)
* [purchasing] Simplify test

* [utils] Move StorageRequest.example up one level

* [purchasing] Load purchases from market

* [purchasing] load purchase states

* Implement myRequest() and getState() methods for OnChainMarket

* [proofs] Fix intermittently failing tests

Ensures that examples of proofs in tests are never of length 0;
these are considered invalid proofs by the smart contract logic.

* [contracts] Fix failing test

With the new solidity contracts update, a contract can only
be paid out after it started.

* [market] Add method to get request end time

* [purchasing] wait until purchase is finished

Purchase.wait() would previously wait until purchase
was started, now we wait until it is finished.

* [purchasing] Handle 'finished' and 'failed' states

* [marketplace] move to failed state once request fails

- Add support for subscribing to request failure events.
- Add supporting contract tests for subscribing to request failure events.
- Allow the PurchaseStarted state to move to PurchaseFailure once a request failure event is emitted
- Add supporting tests for moving from PurchaseStarted to PurchaseFailure
- Add state transition tests for PurchaseUnknown.

* [marketplace] Fix test with longer sleepAsync

* [integration] Add function to restart a codex node

* [purchasing] Set client address before requesting storage

To prevent the purchase id (which equals the request id)
from changing once it's been submitted.

* [contracts] Fix: OnChainMarket.getState()

Had the wrong method signature before

* [purchasing] Load purchases on node start

* [purchasing] Rename state 'PurchaseError' to 'PurchaseErrored'

Allows for an exception type called 'PurchaseError'

* [purchasing] Load purchases in background

No longer calls market.getRequest() for every purchase
on node start.

* [contracts] Add `$` for RequestId, SlotId and Nonce

To aid with debugging

* [purchasing] Add Purchasing.stop()

To ensure that all contract interactions have both a
start() and a stop() for

* [tests] Remove sleepAsync where possible

Use `eventually` loop instead, to make sure that we're
not waiting unnecessarily.

* [integration] Fix: handle non-json response in test

* [purchasing] Add purchase state to json

* [integration] Ensure that purchase is submitted before restart

Fixes test failure on slower CI

* [purchasing] re-implement `description` as method

Allows description to be set in the same module where the
state type is defined.

* [contracts] fix typo

* [market] Use more generic error type

Should we decide to change the provider type later
