Fix bug in FTRawBankDecoder
Bug found. When the estimate for the memory allocation of the FTLiteCluster container is not sufficient, the stored iterators (partitionPoints) are not valid anymore. This happens occasionally (at event 359 in my case).
Thanks to @graven for debugging. Related to !1079 (merged). @sesen @rquaglia @sponce @lohenry @mhadji
