Merge #20535: test: Fix intermittent feature_taproot issue

fa275e1 test: Fix intermittent feature_taproot issue (MarcoFalke)

Pull request description:

  The nodes might disconnect (e.g. due to "Timeout downloading block" https://cirrus-ci.com/task/5313800947630080?command=ci#L1763) and the test fails to continue.

  Fix that by reconnecting the nodes.
