kdepim-addons tests get stuck due to akonadiserver

[Ben Cooksley]

Hi all,

Currently kdepim-addons has at least one test which results in an
Akonadi Server instance being launched.

While this may not seem like a problem, unfortunately the test doesn't
cleanup after itself and shutdown Akonadi Server afterwards. This is
an issue as CTest refuses to continue if a test process leaves any
processes behind, as it assumes the test is still running.

As a consequence of this bug, the CI runs for kdepim-addons regularly
require manual intervention to unstick them.

Could someone take a look please?

Thanks,
Ben
