Merge #13535: [qa] wallet_basic: Specify minimum required amount for listunspent

fa103a5d5e [qa] wallet_basic: Specify minimum required amount for listunspent (MarcoFalke)

Pull request description:

  A value less than that would fail the tests later on anyway:

  ```
  File "./test/functional/wallet_basic.py", line 250, in run_test
      self.nodes[1].sendrawtransaction(signed_raw_tx['hex'])

  test_framework.authproxy.JSONRPCException: bad-txns-in-belowout, value in (1.00) < value out (49.998) (code 16) (-26)
