Merge bitcoin/bitcoin#27378: test: Remove python3.5 workaround

fae66fceb3147385320593d1e15faf290b0f4caf test: Remove python3.5 workaround in authproxy (MarcoFalke)

Pull request description:

  Remove workaround for a bug that is long fixed in a EOL python version, that isn't used by us.

  If the workaround is still needed, it should at least log the exception before silently discarding it, so that debugging is possible/easier.
