Template overrides in Arches Applications are ignored

[chiatt]

If an Arches Application overrides a core Arches template, the override is ignored. The issue occurs here in settings_utils.py which returns only the core arches and project template directories:

arches/arches/settings_utils.py

Line 110 in 9cb2813

os.path.join(Path(__file__).resolve().parent, "app", "templates")
