[SPARK-17104][SQL] LogicalRelation.newInstance should follow the semantics of MultiInstanceRelation
## What changes were proposed in this pull request?
Currently `LogicalRelation.newInstance()` simply creates another `LogicalRelation` object with the same parameters. However, the `newInstance()` method inherited from `MultiInstanceRelation` should return a copy of object with unique expression ids. Current `LogicalRelation.newInstance()` can cause failure when doing self-join.
## How was this patch tested?
Jenkins tests.
