Possibly NPE while reading profile with CommandBeforeFile or CommandAfterFile setting

Current Situation

• With YADE-471 (since 1.12.1) a new attribute
  • enable_for_skipped_transfer for CommandBeforeFile was introduced
  • disable_for_skipped_transfer for CommandAfterFile was introduced
• If you configure a CommandBeforeFile or CommandAfterFile in a profile with an XML editor < version 1.12.1 and run this profile in a YADE job >= version 1.12.1 then these attributes are missing and a NullPointerException is raised while loading the profile.

  ERROR [main] (JadeXml2IniConverter.java:1267) - [CommandAfterFile]java.lang.NullPointerException
  

• This error is not harmful. YADE uses default values with a behavior like before 1.12.1

Desired Behavior

The profile should be load without a NullPointerException
