* Fix mocking multiple http calls in the same function call

Fixes an issue where a function call would perform more than one http request and wait for each to complete before proceeding. The `RequestId` comes from the length of the `requests` collection in the `OffchainState` and if a request is completed before the next one starts it will be removed and the "next expected" will be off by one. This PR tries to fix that by using a request counter that tracks how many requests have been performed so that we can `remove()` items from the `expected_requests` at the right index.

I suspect that this is a sub-optimal soluton and perhaps requests and their mocks should live side by side in the same collection, e.g. in a tuple of `(PendingRequest, Option<ExpectedRequest>)`.

Previously, when publishing ones address onto the DHT, the signature
signing those addresses would be SCALE encoded twice.

This commit removes the second encoding and adjusts the tests
to catch future regressions.

* Start improving `storage_append`

* Fix some stuff

* Fix compilation

* Update docs and add new test

* More tests

* Test kill + append

* Expose that `BasicQueue` expects blocking spawn

Up to now `BasicQueue` expected a closure that to spawn a `Future`.
This was expected to be a closure that spawns a blocking future.
However, this wasn't documented anywhere. This pr introduces a new trait
`SpawnBlocking` that exposes this requirement to the outside.
