`listsinceblock` did not behave correctly when handed a block that was
no longer in the main chain:
/ \
aa1 [tx0] bb1
| |
aa2 bb2
| |
aa3 bb3
Consider a client that has only seen block `aa3` above. It asks the node
to `listsinceblock aa3`. But at some point prior the main chain switched
to the bb chain.
Previously: listsinceblock would find height=4 for block aa3 and compare
this to height=5 for the tip of the chain (bb4). It would then return
results restricted to bb3-bb4.
Now: listsinceblock finds the fork at ab0 and returns results in the
range bb1-bb4.
This test only checks that [tx0] is present.
