* optimize cdp begin blocker by removing unnecessary checks, reusing data and prefix stores in loops, and reducing number of repeated calculations * fix panic for new cdp types if both previous accural time and global interest factor are not set * do not touch global interest factor if no CDP's exist; revert to panic if global interest factor is not found since this is an unreachable state by normal keeper operation -- it can only be reached if store is modified outside of public interface and normal operation
