Remove `previousDepth` in favor of `completedDepth + 2` Beyond the simplification, this could be considered a bugfix from a certain point of view. However, the effect is very subtle and essentially impossible for users to notice. 5372f81cc8 added about 2 Elo at LTC, but only for second and later `go` commands; now, with this patch, the first `go` command will also benefit from that gain. Games under time controls are unaffected (as per the tests).
