Fix CMMCore::saveSystemConfiguration()
Fix CMMCore::saveSystemConfiguration()

This makes it run without errors and also fixes a bug where 'Parent' was
printed 'Property' by mistake.

However this is not a full fix. This function has not been used in a
long time and has further remaining differences with the Java version in
org.micromanager.conf2.
