Fix parameter order for block logs
The new block log params does not known the message number 4 (which is
index 3), therefore LogFormatter::getMessageParameters adds empty index
to keep the sequence in strong order.
But the loop was starting at index 4, not 3, which skips the needed
empty index 3 for the order.
Due to the missing $4 the legacy log params returning index 3 and 4,
therefore move them one up to match the new numbers.
Also fixed undefined index warnings for api's list=logevents
