Correct saving start message in Anomalies; wrap all the save lines in the if condition

Hi @vagudets

I found that I made a silly mistake in the previous development !88 (merged), which added the message when saving data starts in Anomalies, Calibration, Skill modules. The mistake is an if condition in Anomalies. I've corrected it and also changed the if conditions a bit: All the saving lines are in the same if condition, so only when 'save' is not "none", the lines run.

Best,
