Removing the Course-Authoring MFE throws an error during env rendering

[Danyal-Faheem]

When you remove the course-authoring mfe using the method defined here and then run tutor config save, it throws an error. The error is:

Error rendering patch 'openedx-cms-development-settings':
# MFE-specific settings
COURSE_AUTHORING_MICROFRONTEND_URL = "http://{{ MFE_HOST }}:{{ get_mfe('course-authoring')["port"] }}/course-authoring"
CORS_ORIGIN_WHITELIST.append("http://{{ MFE_HOST }}:{{ get_mfe('course-authoring')["port"] }}")

Error rendering template apps/openedx/settings/cms/development.py
Error: Missing configuration value: 'dict object' has no attribute 'port'

This error is likely due to not having a condition in place in the openedx-cms-development-settings patch.
