Describe the bug
Setting logger format to JSON and no_caller to true causes an exception:

To Reproduce

package main

import (
	"github.com/im-kulikov/helium"
	"github.com/im-kulikov/helium/grace"
	"github.com/im-kulikov/helium/logger"
	"github.com/im-kulikov/helium/module"
	"github.com/im-kulikov/helium/settings"
	"github.com/spf13/viper"
	"go.uber.org/dig"
)

var modules = module.Combine(
	helium.DefaultApp, // default application
	grace.Module,      // grace context
	settings.Module,   // settings module
	logger.Module,     // logger module
)

func main() {
	h, err := helium.New(&helium.Settings{
		Defaults: func(v *viper.Viper) error {
			return defaults(v)
		},
	}, modules)
	if err != nil {
		panic(err)
	}

	err = dig.RootCause(h.Run())
	helium.Catch(err)
}

func defaults(v *viper.Viper) error {
	v.SetDefault("logger.format", "json")
	v.SetDefault("logger.no_caller", true)
	return nil
}

Expected behavior
No exception, log format JSON without caller name.
