    CosmicCalculator: fix bug in calling --printparams
    
    Until now, when CosmicCalculator was called with the '--printparams' or
    '-P' option it aborted with an error about not setting the redshift. Whilst
    the redshift value is not mandatory when the user is asking for checking
    the configured parameters.
    
    With this commit, a condition has been added on the check for redshifts at
    the start of the program to let the program continue.
    
    This fixes bug #59400.
