fix: Reduce fallback request before even next block is mined

Browse Source 
Currently it was doing 0.5s + (0.25s x N); now it's 5s + (0.25s x N), assuming 5 block behind is bad enough to request fallback. Also usually fallback "exists" so that it updates last poll time acordingly, so it won't poll much after fallback is triggered.
