[ATR-28927] Bugfix in rates analysis, vector size

Move resizing of chain-group vector, make this the same size as the chains vector which is then used to populate it.

Fixes a crash for the case where the number of chains to process, m_triggers, is smaller than the number of chains configured in the menu, hltmenu.
