40c5886 Fix illegal default `addProxy` and `addrSeparateProxyTor` settings. (251)

Pull request description:

  In f05d349 the value of the `addrProxy` and `addrSeparateProxyTor` settings is set to an illegal default value, because the value of `DEFAULT_GUI_PROXY_PORT ` is passed to the `fieldWidth` parameter of the `QString QString::arg(const QString &a, int fieldWidth = 0, QChar fillChar = QLatin1Char( ' ' )) const` method:

  29fad97c32/src/qt/optionsmodel.cpp (L129)

  29fad97c32/src/qt/optionsmodel.cpp (L139)

  This will create a default proxy setting that consists of 9053 characters and ends with the string `127.0.0.1:%2`.

  This PR attempts to resolve #12623 by setting the correct value for the `addrProxy` and `addrSeparateProxyTor` settings (i) if the proxy setting does not exist; or (ii) if the proxy setting has an illegal value caused by to the aforementioned bug.

  The second condition is *only* relevant if we don't want Bitcoin Core 0.16.0 users to explicitly reset their settings to see the correct default proxy port value.
