Misleading error logs in Settings::fillEmptySettingsWithDefaults()

[BastusIII]

There is an error logged each time Settings::fillEmptySettingsWithDefaults() is called, if there are no default settings files found under the relative path "resources/<default_settings_filename>".
This error is logged also if a settings file is found under CMAKE_JOYNR_SETTINGS_INSTALL_DIR.

As the constructors of WebSocketSettings and others call Settings::fillEmptySettingsWithDefaults(), each time one of those settings instances is created, this error is logged.

[error] Settings Could not read settings file: resources/default-websocket.settings: cannot open file

Please remove this log message by checking if the paths exists before, or reduce the log-level.

Thanks for the analysis and for reporting the issue. Indeed the error is misleading, it would be nice if you can make a pull-request.
