fix: syncer spamming RPC and reaching tip of chain

[joanestebanr]

When any synchronize exceeds the block finalized keep asking continously for same range without any sleep, and don't extend the range to reach the lastest block

expected

• The idea is to extend the range to go to the lastest block seen on network,
  Here the explanation of how must work the range when we are > finalized:

Ask logs for current range [ n - m ]

• Returns log block x -> next_range = [ x - ( x+ block_chunk) ]
• Returns empty:
• if ( fbn - n > block_chunck ) -> create empty block with getHeader(fbn+block_chunk)
• we have enough blocks on finalized zone to create a empty block
• next_range = [ (fbn + block_chunck) - m + block_chunck ]
• else
• We just increase the range:
• next_range = [ n - m + block_chunck ]
