A small tweaked version of Bundler.with_clean_env
Bundler has Bundler.with_clean_env by its own, but the method replace ENV with ENV captured on starting. cf. github.com/bundler/bundler/blob/e8c962ef2a3215cdc6fd411b6724f091a16793d6/lib/bundler.rb#L230 Server::Starter
changes ENV during running to communicate with child processes, so we need to keep the changed ENV. This is why I needed this small tweaked version
