Using an inherited config from the DEFAULT profile crashes the app with RecursionError

[jkells]

Expected Behavior

Using the following configuration file

[base-profile]
okta_username = user@example.com

[prod]
inherits = base-profile
app_url = https://example.com/app_url/prod

[DEFAULT]
inherits = base-profile
app_url = https://example.com/app_url/prod

Running gimme-aws-creds should use the default profile but instead crashes.

Current Behaviour

The app crashes with the following exception:

RecursionError: maximum recursion depth exceeded while calling a Python object

This looks like a regression as our current config file uses this format and started failing after an update.

Your Environment

OSX Mohave, running gimme-aws-creds 2.3.4 from homebrew.

I am also seeing this issue after having to upgrade to 2.4.3 due to the okta change.
