Combining empty help_text in model field + gettext_lazy will make new migrations every time we run makemigrations

[Javier Matos Odut]

I have seen that in my project, setting help_text for model field as gettext_lazy with empty string will create new migrations as many times as you run makemigrations command, even when there are no changes.

from django.db import models
from django.utils.translation import gettext_lazy as _

# Create your models here.

class MyModel(models.Model):
    id = models.AutoField(primary_key=True)
    my_field = models.CharField(max_length=2, help_text=_(''))

Then do python manage.py makemigrations and it will create migration files forever.

I know using empty string for gettext_lazy is a nonsense, but it should not behave that way.
