quassel: Don't handle certificates if not installed
Tests:

- Without these changes, with Quassel not-installed, change the domain name.
Notice that certificate events for Quassel fails due to missing domain
information.

- With these changes, with Quassel not-installed, change the domain name. Notice
that certificate events for Quassel don't result in any actions.

- With these changes, when Quassel is installed, certificate is properly setup
for a domain.

- With these changes, with Quassel installed, change the domain name. Notice
that certificate events for Quassel succeed.
