Previously, we only took the new head if it's heavier than the last head. Unfortunately, this meant that F3 finalization wasn't properly propagated to the miner. In terms of impact: 1. It seems likely that this check was simply defensive as, prior to F3, the new head should never have a lower weight (unless you're talking to multiple lotus nodes, I guess...). 2. The `lastWork` field is mostly used to track null blocks. Worst-case scenario, if we switch heads, we'll attempt to re-mine previous heights. However, that should be relatively fast and, due to the slash filter, we won't attempt to re-broadcast any of those blocks. Signed-off-by: Jakub Sztandera <oss@kubuxu.com>

We also perform this check inside `SyncSubmitBlock` so we did have an effective filter, but this was still wrong. Signed-off-by: Jakub Sztandera <oss@kubuxu.com>
