CPAlgorithms: Fix config printout
@zalegria pointed out that the wrong settings were printed in the configuration of blocks when there were no user settings overriding defaults, but the __init__
of the config block itself was used to override these defaults. This is the case for instance with
self.setOptionValue("skipOnData", True)
in a number of config blocks. This MR fixes only the printing of the options (everything else is correctly handled).
