Gareth Kirwan 1212b6750e OrderManager: Fix race condition in submit with ws (#1336)
* OrderManager: Fix race condition in submit with ws

If the ws sees the order before processSubmittedOrder then it will have
assigned it an internal order id already and added it to the store.
Don't treat that as an error. Instead just use the newer ws details

* OrderManager: Fix error comparisson

Should always use errors.Is when possible

* Tests: Simplify btcusd test pair declaration

* OrderManager: Improve test readability

* OrderManager: Add orderstore.getByDetail test

* Return a fresh pointer from orderstore.getByDetail

This protects the order.Details in the store from direct access.
The use-case was to allow the returned objects to be references so that
future changes to them would be reflected.
However we're not ready yet to allow people to touch the orders
directly, because they're not protected directly by a mutex, and nothing
would stop consumers contaminating the integrity of the data.

We can revisit this topic later atomicly, but it's definitely tangental
to the cause of action for PR #1336.

* Fix GetByDetail tests to assert a new pointer

* OrderManager: Avoid possible lock races

This fix internalises the getByDetail because the implication of moving
lock ownership out of exists/getByDetail to consumers breaks the order
store struct encapsulation in a way we really don't want to.
It's also more efficient

* Fix spelling mistake

* OrderManager: Improve clarity of comment
