gc v2 tests (#512)

* set MaxBlockCount at init 
* properly calculate total size
* basic blockstore compact blocks test
* correct detection of block swap
* Use one implementation for CreateRandomBlob
* reduce some data sets to increase speed of tests
* reduce test time
* rename BlockStoreCompactState::AddBlock -> BlockStoreCompactState::IncludeBlock
