Airflow novice here trying to build a simple workflow where an upstream
task decides whether to follow an 'upload' branch or proceed directly to
subsequent join >> finish tasks. Regardless of whether branch callable
returns 'branch_skip_upload' or 'branch_skip_upload', tasks 'join',
'finish' are skipped - and I want these two tasks to always execute.

What am I doing incorrectly?
