chore(frontend): add test for delta join with projection

[skyzh]

Signed-off-by: Alex Chi [email protected]

What's changed and what's your intention?

As title. Anyway, if there's projection between HashJoin and IndexScan, then the plan cannot be converted to delta join (for now). This PR adds test for projection outside join.
