[SPARK-13456][SQL][follow-up] lazily generate the outer pointer for case
class defined in REPL
## What changes were proposed in this pull request?
In https://github.com/apache/spark/pull/11410, we missed a corner case:
define the inner class and use it in `Dataset` at the same time by using paste
mode. For this case, the inner class and the `Dataset` are inside same line
object, when we build the `Dataset`, we try to get outer pointer from line
object, and it will fail because the line object is not initialized yet.
This PR make the process of getting outer pointer from line object lazy, so
that we can successfully build the `Dataset` and finish initializing the line
object.
## How was this patch tested?
todo (how to simulate the past mode in our repl suite?)
