Minor fix to avoid duplicate calls of timer startup

- Retrieving the blockchain stat and marketcap info was set to run in a manner that could trigger it multiple times, and if the initial page launched was the explorer, it could sometimes crash as the "BlockchainStats" was not in cache.
- Rename the docker-compose, was invalid named.

Docker/Nako/docker.compose.yml → Docker/Nako/docker-compose.yml
