node1 (with 24 blocks) causes node0 (with 6 blocks) to silently
reorg. so move the subtest to a point before the 20 blocks are
generated so that node1's state doesn't cause node0 to silently
reorg.
when we reconsiderblock, previously only block and it's
descendants were considered as chain tip candidates/inserted into
setBlockIndexCandidates
ex: on this chain, with block 4 invalidated
1 -> 2 -> 3 -> 4 -> 5 -> 6 -> header 7
blocks 4, 5, 6, header 7 have BLOCK_FAILED_* flags set
previously:
- if we reconsiderblock header 7, the chain would have all the
BLOCK_FAILED_* flags cleared but would report chain tip as block 3.
- after restart, it reports correct chain tip block 6.
now:
- if we reconsiderblock header 7, the correct chain tip block 6 is
reported since ancestors are also considered as chain tip
candidates/inserted into setBlockIndexCandidates.

Without doing so, header-only chains building on a chain that
will be marked as invalid would still be eligible for m_best_header.
This improves both getblockchaininfo and getchaintips behavior.
While this adds an iteration over the entire block index, it can only be
triggered by the user (invalidateblock) or by others at a cost (the
header needs to be accepted in the first place, so it needs valid PoW).

This means that it is being called in two situations:
1.) As part of the invalidateblock rpc
2.) When we receive a block for which we have a valid
header in our block index, but the block turns out to be invalid
The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.
