eeeef80fb6 qa: Fix some TODOs in p2p_segwit (MarcoFalke)

Pull request description:

  * I believe we don't need to redundantly test versionbits logic in every functional tests that tests a softfork deployment that is being done with versionbits. Thus, remove two `TODO`s that ask for that.
  * Replace another `TODO` with `wait_until`.
  * Some style fixups after #13467
