Adapted more algorithms to the replacement of KeyContainer <Track> by std::vector<Track>

Namely :
  - TrackAddLikelihood
  - TrackBestTrackCreator
  - TrackBuildCloneTable
  - TrackEraseExtraInfo
This allows some tests that are failing in the TDR branch to go further.
However, they now fail with a segfault in LinkerWithKey called by TrackBuildCloneTable.
This is due to the fact that we have broken the linking (+ lack of checking when dereferencing...). A know issue
