environs/local: destroy-environment fails to shut down the mongodb server provided by juju-mongodb package

In T we use the version of mongodb provided by `juju-mongodb`. Juju cannot shutdown this mongodb server when it runs on the local machine

ubuntu@winton-02:~$ juju destroy-environment -y local
ubuntu@winton-02:~$ juju status
ERROR Unable to connect to environment "local".
Please check your credentials or use 'juju bootstrap' to create a new environment.

Error details:
no CA certificate in environment configuration

ubuntu@winton-02:~$ juju status^C
ubuntu@winton-02:~$ bash deploy.bash
+ /home/ubuntu/bin/juju destroy-environment -y local
ERROR failed to destroy environment "local"

If the environment is unusable, then you may run

    juju destroy-environment --force

to forcefully destroy the environment. Upon doing so, review
your environment provider console for any resources that need
to be cleaned up.
