Enhance Makefile

[lusoalex]

When using Make gravitee for the first time, we have an error:

/bin/sh: line 0: cd: .working/compose: No such file or directory
ERROR:
        Can't find a suitable configuration file in this directory or any
        parent. Are you in the right directory?

        Supported filenames: docker-compose.yml, docker-compose.yaml

This is because there's nothing to stop and clean, as there is no working dir yet.

This PR will check if the working dir exists, if not, it will skip the stop & prune steps.

Regards,
Alexandre.
