Fix job crashing for 9 time-bin FST data (#634)

Issue #631 was due to an inconsistent number of time bins used in the
data and the codes.
In most FST data and in the codes, we used 3 time bins, while some data
used 9 time bins.
Only changing a constant in `StRoot/StEvent/StFstConsts.h` is needed to
fix this issue.
