simplify_expr() invoke nullable() exist bug #5191

Description

@jackwener

Describe the bug
When invoke nullable(), if plan is semi/anti join, all_schema() only just contain one side child output.
If we want to compute expr, it will fail.
like:

t1 semi join t2 on t1.id = t2.id

due to schema just is [t1.id] (join), [t1.id](left) , [t2.id] (right).

so t1.id = t2.id can't invoke nullable()
