passing an empty string to help_text in model fields using ugettext_lazy causes new migrations without any change

[Mohamad A.]

A sample of the error would be something like the following

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

class sample(models.Model):
    sample_field = models.CharField(max_length=5, help_text=_(""))

Executing makemigrations command generates new migration file without any change in the contents.
The previous model generates the following migration file:

from django.db import migrations, models


class Migration(migrations.Migration):

    dependencies = [
        ('mig', '0005_auto_20191029_1638'),
    ]

    operations = [
        migrations.AlterField(
            model_name='sample',
            name='sample_field',
            field=models.CharField(help_text='', max_length=5),
        ),
    ]
