add close function to storage interface
add common defer function call which will close db connection
remove context as soon as it's not needed anymore
updated unit tests
* Fixed small incosistencies related to comments and variable name
* For testing purposes we have to move the method newBlockchain from the cli/server/server.go to pkg/core/blockchain.go. In addition we have to rename it to NewBlockchainLevelDB in order to be able to export it and avoid naming conflicts. In future we still need to think how to switch between different blockchain implementation easily but for the time being this is not possible.
