Add test for missing staticfiles.json
## Code Before:
from io import StringIO

from django.core.management import call_command
from django.test import TestCase


class PipelineTestCase(TestCase):

    def test_success(self):
        call_command('collectstatic', '--noinput', stdout=StringIO())
        call_command('clean_staticfilesjson', stdout=StringIO())

## Instruction:
Add test for missing staticfiles.json
## Code After:
import os
from io import StringIO

from django.conf import settings
from django.core.management import call_command
from django.core.management.base import CommandError
from django.test import TestCase


class PipelineTestCase(TestCase):
    def setUp(self):

        if os.path.isfile(file_path):
            os.remove(file_path)

    def test_success(self):
        call_command('collectstatic', '--noinput', stdout=StringIO())
