75a9305 Fix intermittent test failures due to missing sync_all (Samuel Dobson)
eb02dbb Use self.generate not node.generate throughout tests (Samuel Dobson)

Pull request description:

  After bitcoin#17211 was merged, there have been a few intermittent test failures in `wallet_send.py`, `rpc_fundrawtransaction.py`, and `rpc_psbt.py`

  I believe all these failures are due to these missing `sync_all()`s
