Merge Sonar invocation back to ci.yml

For coverage analysis to work, a test run is needed, making the overlap
between ci.yaml and sonar.yml quite significant again.

Note: 'update-api' option is temporarily dropped from the matrix
to speed up the check. If things run fine, 'update-api' will come back.
