run_instance needs to allow run both sync and server tasks

Currently run_instance.sh stops the other one
that's because CONTAINER_NAME=hivemind-instance is fixed

I actually had this issue moments ago, Used the docker-options to specify a custom name as a workaround. I'm running on the 1.27.4.0 tag.

It's work mentioning that the readme could do with updating to add a note in the pre-built instance container section that you will need to run a seperate instance for server to access the hivemind api.
