[MINOR] [SQL] Fix error message string in nullSafeEvel of TernaryExpression
## What changes were proposed in this pull request?
TernaryExpressions should thows proper error message for itself.
```scala
protected def nullSafeEval(input1: Any, input2: Any, input3: Any): Any =
- sys.error(s"BinaryExpressions must override either eval or nullSafeEval")
+ sys.error(s"TernaryExpressions must override either eval or nullSafeEval")
```
## How was this patch tested?
Manual.
Author: Dongjoon Hyun <dongjoon@apache.org>
Closes #12642 from dongjoon-hyun/minor_fix_error_msg_in_ternaryexpression.
