Currently, when domains is for an app's LE component is set as '*'. Calling
setup_certificates() results in copying certificate for the '*' domain instead
copying certificates for each of the domains on the system. Fix this by
implementing a special case where certificates are copied for all domains that
can have certificates.
Tests:
- Implement and run unit tests.
- Certificates are copied to /etc/{postfix,dovecot}/letsencrypt/ when email
server uses LE components with '*' for domains parameter.
