SafeWriteConfig() fails if file does not exist

[TWinsnes]

When calling viper.SafeWriteCofig() it fails with a file not found error.

Test code attached.

package main

import (
	"fmt"
	"os"

	"github.com/spf13/viper"
)

func main() {
	viper.AddConfigPath("/tmp")
	viper.SetConfigName("filename")
	viper.SetConfigType("yaml")
	viper.SetDefault("LogLevel", "Info")

	fmt.Println("Writing Config file!")
	err := viper.SafeWriteConfig()

	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}

	fmt.Println("wrote config file")
}

Output:

Writing Config file!
Config File "filename" Not Found in "[/tmp]"

Expected output:

Write Config file!
wrote config file

Currently the documentation for SafeWriteConfig is quite misleading 😅

SafeWriteConfig writes current configuration to file only if the file does not exist.

This is issue is also present for SafeWriteConfigAs

This is fixed in #450

Use viper.SetConfigFile("filename.yaml") instead of viper.SetConfigName("filename") then SafeWriteConfig and SafeWriteConfigAs() will work
