Fix watchman default status check to no return an error

[jonespm]

Expected behavior (A description of what you expected to happen) :

When you call /status it shoudn't have any errors by default. Currently we workaround this with the the URL

/status/?skip=watchman.checks.storage but it would be nice it it worked.

Describe the bug (Tell us what happens instead of the expected behavior) :

There's a stacktrace in the storage section and it returns an error. It would be nice to fix this so we don't have to workaround it.

  "storage": {
    "ok": false,
    "error": "Could not find config for 'default' in settings.STORAGES.",
    "stacktrace": "Traceback (most recent call last):\n  File \"/usr/local/lib/python3.10/site-packages/django/core/files/storage/handler.py\", line 35, in __getitem__\n    return self._storages[alias]\nKeyError:

I think this might be fixed by just configuring a placeholder InMemoryStorage like. The better if the watchman library checked to see if this was configured or handled the exception and just didn't print anything for storage. But this should work for us

STORAGES = {
    'default': {
        'BACKEND': 'django.core.files.storage.InMemoryStorage',
    },
}

Steps to Reproduce :

1. Startup MyLA and go to the URL for /status and /status/bare_status. You should get a 200 response and no errors.
