  Remove docker container on build failure

Description

It fixed an error where the docker container was left in an improper state after a build failure.
When a failure occurred during contract build, the container was left in an improper state. So, even when the user attempted to compile the contract with the fix, the build still failed due to the incorrect container state after the first build.
