[SPARK-19724][SQL][FOLLOW-UP]Check location of managed table when
ignoreIfExists is true
## What changes were proposed in this pull request?
In the PR #20886, I mistakenly check the table location only when
`ignoreIfExists` is false, which was following the original deprecated PR.
That was wrong. When `ignoreIfExists` is true and the target table doesn't
exist, we should also check the table location. In other word,
**`ignoreIfExists` has nothing to do with table location validation**.
This is a follow-up PR to fix the mistake.
## How was this patch tested?
Add one unit test.
