Should stop running containers before updating

[Thegaram]

I started a local node, then a got prompted to update to v0.4.2, so I updated. When I wanted to run a local node again, I got this error:

> docker run -it --rm --name conflux-dev-node-0.6.3 -p 12535:12535 -p 12536:12536 -p 12537:12537 -v conflux-dev-node:/conflux-node -w /conflux-node --entrypoint conflux confluxchain/conflux-rust:0.6.3 --config default.toml
docker: Error response from daemon: Conflict. The container name "/conflux-dev-node-0.6.3" is already in use by container "5103ff323c978b903a50595466126a22a1c20b32cf57126aa58829925e08a270". You have to remove (or rename) that container to be able to reuse that name.
See 'docker run --help'.

So I had to stop that container manually. Conflux Studio should stop all running containers before updating.

It would also be nice if Conflux Studio could handle such common Docker errors automatically, they are confusing for beginners who are not familiar with Docker.
