When I attempt to run burn_in_tests.py locally, the wrong tests are chosen. Here is a snippet of the logs, showing only tests that are untracked in git:

[2020-03-13 17:20:15,455 - __main__ - DEBUG] 2020-03-13 17:20.15 Found changed tests            files={'jstests/replsets/oplog_sampling1.js', 'jstests/concurrency/fsm_workloads/collreindex.js', 'jstests/noPassthrough/duplicate_key_get_last_error.js', 'jstests/sharding/create_collection_prepared_transactions.js'}

Ideally, I would like local burn_in_tests.py to locally run all modified tests since master, including those that are already committed in the local branch, without needing to generate evergreen task configs.
It is my understanding that presently, local burn_in_tests.py will not run any tests that are committed in the local branch, even if they are not part of master.
