We have two similar blockchain APIs: GetNextBlockValidators and GetValidators. It's hard to distinguish them, thus renaming it to match the meaning, so what we have now is: GetNextBlockValidators literally just returns the top of the committee that was elected in the start of batch of CommitteeSize blocks batch. It doesn't change its valie every block. ComputeNextBlockValidators literally computes the list of validators based on the most fresh committee members information got from the NeoToken's storage and based on the latest register/unregister/vote events. The list returned by this method may be updated every block. Signed-off-by: Anna Shaleva <shaleva.ann@nspcc.ru>
