OMNeT++ 6.1 compatibility fix: Comment out usage of record-vector-results

The `record-vector-results` setting causes a runtime error in OMNeT++ versions prior to 6.2.
Commenting out the line ensures compatibility with version 6.1.

Also added
  **.vector-recording = false
  **.vector-record-empty = false
for disable the lots of vector recordings
