2ab7952bda8d15e91b03f8307839030cbb55614e test: add bip157 coverage for (start height > stop height) disconnect (Sebastian Falbesoner)
63e90e1d3f5ed08f9871f07667d389ec66aa621c test: check for specific disconnect reasons in p2p_blockfilters.py (Sebastian Falbesoner)

Pull request description:

  This PR checks for specific disconnect reasons using `assert_debug_log` in the functional test `p2p_blockfilters.py`. With that we ensure that the disconnect happens for the expected reason and also makes it easier to navigate between implementation and test code, i.e. both the questions "do we have test coverage for this disconnect cause?" (from an implementation reader's perspective) and "where is the code handling this disconnect cause?" (from a test reader's perspective) can be answered simply by grep-ping the corresponding debug message.

  Also, based on that, missing coverage for the (start height > stop height) disconnect case is added:
