[SPARK-15094][SPARK-14803][SQL] Remove extra Project added in EliminateSerialization
## What changes were proposed in this pull request?
We will eliminate the pair of `DeserializeToObject` and `SerializeFromObject` in `Optimizer` and add extra `Project`. However, when DeserializeToObject's outputObjectType is ObjectType and its cls can't be processed by unsafe project, it will be failed.
To fix it, we can simply remove the extra `Project` and replace the output attribute of `DeserializeToObject` in another rule.
## How was this patch tested?
`DatasetSuite`.
