Merge bitcoin/bitcoin#25430: test: refactor: save MiniWallet mode explicitly

Browse Source 
be8d0dba15 test: refactor: save MiniWallet mode explicitly (Sebastian Falbesoner)

Pull request description:

  Rather than abusing the member variables `self._priv_key` and `self._address` to determine the MiniWallet mode, save it explicitly (`self._mode`) in the constructor and use that instead to increase the readability and maintainability of the code.
