Fix crash when Hlt1LambdaLLDetachedTrack or Hlt1XiOmegaLLL are run alone

Kate Abigail Richardsonrequested to merge
kaaricha_indiv_line_fix into master

While running the line independence test, I observed that running Hlt1LambdaLLDetachedTrack and Hlt1XiOmegaLLL alone caused a crash. The solution was found by @thboettc, many thanks!
