This commit adds a test for the FilteredChainView interfaces,
making sure they notify about disconnected/connected blocks
in the correct order during a reorg.
This commit reduces the neutrino.WaitForMoreCFHeaders parameter when
instantiating a neutrino instance as a lower value will allow the tests
to complete more quickly.
This commit adds a new set of behavioral interface level tests to the
chain view package. This set of tests can now be used in order to check
proper conformity to this “specification” for all future
implementations of the chain view package.
