Load config SUPER_USER_CHAPTER_NAME as a string.

@DSASanFrancisco/portal-members

SUMMARY

The database configuration was incorrectly attempting to parse the environment variable as an int, but it's supposed to be a string. This will make the app crash on boot if a valid value is present in this environment variable:

Traceback (most recent call last):
  File "/usr/src/app/config/lib.py", line 142, in validate
    return as_type(value) if convert is None else convert(value)
ValueError: invalid literal for int() with base 10: 'San Francisco DSA'

The above exception was the direct cause of the following exception:
