[MIRROR] Fixes source of tgui errors in accounts console [MDB IGNORE]…

* Fixes source of tgui errors in accounts console (#79048)

## About The Pull Request

It's possible to have bank accounts created with `null` jobs. This
results in a runtime bluescreen that breaks the account management
console for the whole round.

The runtime comes from trying to access `title` from the null job datum
in `ui_data()` which results in the ui data not being sent.
