With repeated calls to
check_until, provers are expected to start from their current state. Bmc and KInduction did this correctly, see here. However, the main loop always started from 0, for example here. This made the logger messages appear to be repeating work. This PR fixes that by starting the loop from the next target.reached_k_is the highest already checked bound, so the next one to work on isreached_k_ + 1.
