[SPARK-16715][TESTS] Fix a potential ExprId conflict for SubexpressionEliminationSuite."Semantic equals and hash"
## What changes were proposed in this pull request?
SubexpressionEliminationSuite."Semantic equals and hash" assumes the default AttributeReference's exprId wont' be "ExprId(1)". However, that depends on when this test runs. It may happen to use "ExprId(1)".
This PR detects the conflict and makes sure we create a different ExprId when the conflict happens.
## How was this patch tested?
Jenkins unit tests.
