Test Plan titles not updating if `aria-at/references.csv`'s title is changed

[howard-e]

When w3c/aria-at updates a test plan's title through the respective /data/references.csv, the change isn't reflected throughout the app (given that the directory name has not been changed)

2 likely reasons here:

1. The TestPlanVersion.title should have long been deprecated and prefer the title coming from TestPlan.title. Both tables linked through directory. TestPlanVersion.title is most likely still being widely used
2. When the test plan's title, is updated and the directory name has remained unchanged, there is no mechanism to push that update to the TestPlan table which would then propagate the change app-wide, given that (1) above has been resolved. This change should most likely be done at server/scripts/import-tests/testPlanVersionOperations/getOrCreateTestPlan.
