Wait for AsyncResult::finished signal.

Intended usage is something like this:

NoteStore* ns;
Note note;
...
QObject::connect(ns->createNoteAsync(note), &AsyncResult::finished, [](QVariant result, QSharedPointer<EverCloudExceptionData> error) {
    if(!error.isNull()) {
        // do something in case of an error
    } else {
        Note note = result.value<Note>();
        // process returned result
    }
});
