Code reproducing the issue

viper.SetConfigName("testfile")
viper.SetConfigType("yaml")
viper.AddConfigPath("/dir/dir2/testfile")

Expected Behavior

When searching if file exists, file path should only be searched with list of available extension and custom extension if provided in config.

Actual Behavior

In line 86 in file.go , extension is not added while checking exists so incorrect files will be matched.
