This commit fixes a bug discovered by Neza; if the track finding finds exactly zero tips, it never sets the total number of track candidates to zero, which causes it to use an uninitialized value in a later kernel. This, in turn, leads to an assertion error. In this commit, we fix the bug and add an assertion to protect against any future errors. Co-authored-by: Neža Ribarič <neza.ribaric@cern.ch>
