coverage xml isn't created

[jokiefer]

Environment

• Python version: 3.7
• django-nose version: 1.4.7

Steps to Reproduce

1. Configure django nose in settings.py:

TEST_RUNNER = 'django_nose.NoseTestSuiteRunner'
NOSE_ARGS = [
    '--with-xunit',
    '--xunit-file=xunit-result.xml',
    '--with-coverage',
    '--cover-erase',
    '--cover-xml',
    '--cover-xml-file=coverage-report.xml',
]

2. run command python manage.py test --where "tests/unit_tests/"

Expected Behavior

coverage-report.xml is created properly

Observed Behavior

coverage-report.xml isn't created properly. Instead of creating the coverage-report.xml file there is still a .coverage temp file.

If i run the command without the --where parameter it works properly.
