Cleanup integration tests (#757)
* integration: move REST API tests into their own module

* integration: move upload and download tests into their own module

* integration: move purchasing tests into their own module

* integration: move marketplace tests to the right module

* integration: mine a block *after* starting nodes

To ensure that tests involving multiple nodes do
not start with out-of-sync clocks

* Fix: do not swallow CancellationErrors

* integration: avoid underflow in UInt256

* network: remove unnecessary error handling

No Exceptions can occur, only Defects, because everything
is asyncSpawned.

* network: do not raise in asyncSpawned proc
