Thanks for @gatorsmile 's help.
`ConstantFolding` will affect other test cases in
`FoldablePropagationSuite`.
It's fine without adding `ConstantFolding`.
Before fix:
```
[info] !'Join Inner, ((a#0 = a#0) && (1 = 1)) 'Join Inner, (('tb.a
= 'ta.a) && ('tb.tag = 'ta.tag))
[info] !:- Union :- 'SubqueryAlias ta
[info] !: :- Project [a#0, 1 AS tag#0] : +- 'Union
[info] !: : +- LocalRelation <empty>, [a#0, b#0] : :- 'Project
['a, 1 AS tag#0]
[info] !: +- Project [a#0, 2 AS tag#0] : : +-
LocalRelation <empty>, [a#0, b#0]
[info] !: +- LocalRelation <empty>, [a#0, b#0] : +- 'Project
['a, 2 AS tag#0]
[info] !+- Union : +-
LocalRelation <empty>, [a#0, b#0]
[info] ! :- Project [a#0, 1 AS tag#0] +- 'SubqueryAlias tb
[info] ! : +- LocalRelation <empty>, [a#0, b#0] +- 'Union
[info] ! +- Project [a#0, 2 AS tag#0] :- 'Project
['a, 1 AS tag#0]
[info] ! +- LocalRelation <empty>, [a#0, b#0] : +-
LocalRelation <empty>, [a#0, b#0]
[info] ! +- 'Project
['a, 2 AS tag#0]
[info] ! +-
LocalRelation <empty>, [a#0, b#0] (PlanTest.scala:99)
```
After fix:
```
[info] !'Join Inner, ((a#0 = a#0) && (tag#0 = tag#0)) 'Join Inner,
(('tb.a = 'ta.a) && ('tb.tag = 'ta.tag))
[info] !:- Union :- 'SubqueryAlias
ta
[info] !: :- Project [a#0, 1 AS tag#0] : +- 'Union
[info] !: : +- LocalRelation <empty>, [a#0, b#0] : :- 'Project
['a, 1 AS tag#0]
[info] !: +- Project [a#0, 2 AS tag#0] : : +-
LocalRelation <empty>, [a#0, b#0]
[info] !: +- LocalRelation <empty>, [a#0, b#0] : +- 'Project
['a, 2 AS tag#0]
[info] !+- Union : +-
LocalRelation <empty>, [a#0, b#0]
[info] ! :- Project [a#0, 1 AS tag#0] +- 'SubqueryAlias
tb
[info] ! : +- LocalRelation <empty>, [a#0, b#0] +- 'Union
[info] ! +- Project [a#0, 2 AS tag#0] :- 'Project
['a, 1 AS tag#0]
[info] ! +- LocalRelation <empty>, [a#0, b#0] : +-
LocalRelation <empty>, [a#0, b#0]
[info] ! +- 'Project
['a, 2 AS tag#0]
[info] ! +-
LocalRelation <empty>, [a#0, b#0] (PlanTest.scala:99)
```
I just fix the test case(`"tb.tag" -> "tb.tag".attr`).
