[SPARK-16415][SQL] fix catalog string error
## What changes were proposed in this pull request?
In #13537 we truncate `simpleString` if it is a long `StructType`. But
sometimes we need `catalogString` to reconstruct `TypeInfo`, for example in
description of [SPARK-16415
](https://issues.apache.org/jira/browse/SPARK-16415). So we need to keep the
implementation of `catalogString` not affected by our truncate.
## How was this patch tested?
added a test case.
