Merge #16263: qt: Use qInfo() if no error occurs

a2aabfb749 Use qInfo() if no error occurs (Hennadii Stepanov)

Pull request description:

  [Warning and Debugging Messages](https://doc.qt.io/qt-5/debug.html#warning-and-debugging-messages):
  > - `qInfo()` is used for informational messages.
  > - `qWarning()` is used to report warnings and recoverable errors in your
  application.
  >
  > If the `QT_FATAL_WARNINGS` environment variable is set, `qWarning()` exits after printing the warning message. This makes it easy to obtain a backtrace in the debugger.

  [`qWarning()`](https://doc.qt.io/qt-5/qtglobal.html#qWarning):
  > Calls the message handler with the warning message message... This function does nothing if `QT_NO_WARNING_OUTPUT` was defined during compilation; it exits if at the nth warning corresponding to the counter in environment variable `QT_FATAL_WARNINGS`.

  This PR allows more productive debugging using the environment variable `QT_FATAL_WARNINGS`.

  Examples:
  - https://github.com/bitcoin/bitcoin/pull/16118#issuecomment-503184695
  - https://github.com/bitcoin/bitcoin/pull/16254#issuecomment-504223404

  The behavior, when option `-debug=qt` is set/unset, remains unchanged.
