[Code health] Add test coverage for adhoc data submission flow

[shobhitagarwal1612]

Fixes #2502

This is a no-op change and adds test coverage for data submission flow when LOI isn't provided and needs to be created along with the whole flow (incl. LoiDialogName handling).

Also adds a couple of TODOs for detected code smells.

Increases overall coverage by 1.28%. See codecov reports #2980 (comment).
