cmake support for tst_moc

We use qt_wrap_cpp instead of AUTOMOC so that we can easily find the
json files.
Getting autorcc to run only after json file has been generated was
deemed too tricky.  Therefore the test is slightly modified to check for
the json files in its directory instead of the resource, if the qrc file
does not exist.
