8a20f765cc test: drop duplicate getaddrs from p2p_getaddr_caching (Martin Zumsande)
feb0096139 test: fix intermittent failure in p2p_getaddr_caching (Martin Zumsande)

Pull request description:

  Fixes #28133

  In the consistency check, it's not enough to check that our address/port is unique, only the combination of source and target must be unique. Otherwise, the OS may reuse ports for connections to different `-addrbind`, which was happening in the failed runs.

  While at it, the second commit cleans up duplicate `getaddr` messages in `p2p_getaddr_caching.py` that do nothing but generate `Ignoring repeated "getaddr"` log messages (and cleans up some whitespace the python linter complains about).
