Blockchain: cancel pop_blocks() operation on interupt

Browse Source 
On SIGINT, `Blockchain::cancel()` is called, which sets `m_cancel` to `true`.
This commit stops attempting to pop blocks from the chain once that flag is
set. This should leave the blockchain in a well-define state, even if the
`pop_blocks()` operation itself did not "complete".
