Added Akonadi version check for some renamed components

[dragotin]

This PR contains Akonadi version checks for components that were renamed in Akonadi version 5.24. Akonadi renamed the contact viewer and editors namespace.

With this PR, that should be automatically detected and build should work for version from 5.24 on but also older releases.

Note for old Akonadi that still has the KF5 instead of KPim5 prefix, cmake must be called with a build switch:

cmake -DAKONADI_LEGACY_BUILD=ON ..

See #209
