Merge #12512: Don't test against the mempool min fee information in mempool_limit.py

55f89da Don't test against the mempool min fee information in mempool_limit.py (Ben Woosley)

Pull request description:

  Because the right-hand side of this comparison can be influenced
  externally, e.g. via the -maxmempool argument, the existing mempool state,
  host memory usage, etc.
