An attempt to get `accuracy` key results in SystemExit

Description

media_serializer calls super.to_representation(). For tags field, when the tag does not contain accuracy, it can raise an error that breaks the app and causes a SystemExit.

I am not sure why it would look for accuracy in tags even though accuracy is set as not required:

TagSerializer(allow_null=True, help_text='Tags with detailed metadata, such as accuracy.', many=True):
    name = CharField(help_text='The name of a detailed tag.')
    accuracy = FloatField(help_text='The accuracy of a machine-generated tag. Human-generated tags do not have an accuracy field.', required=False)

Reproduction

I will try to reproduce and update the issue.

Since this error

• occurred only once in the last month
• did not reappear in the five days since the first incident
• shows an incorrect traceback where the uncaught exception has a catch clause
• cannot be reproduced by making the same request that caused it in the first place

I'm lowering the priority to low. If it still doesn't appear in the future, we'll close it.

I ignored it in Sentry until it appears 10 times more. Reopen in that case.
