The mkdir ownership rule prepended `sudo` to chown/chmod, and the &&
rule then added another, producing `sudo sudo`. That fails on hosts
like Alpine, where root is not in sudoers. Both parseCommandsByLineForSudo
and parseLineForSudo now leave the prefix to the && rule.
Also:
- Fix the `App\Helpers\SSLHelper` reference in RegenerateSslCertJob to
`SslHelper`, so it autoloads on case-sensitive filesystems.
- Stop StartPostgresql and StartMongodb from overriding the configuration
dir with a hardcoded Docker volume path in development.
- Add tests for nested sudo behaviour, the class reference letter case
and database configuration dirs in development.
