[SPARK-25883][SQL][Minor] Override method `prettyName` in `from_avro`/`to_avro` ## What changes were proposed in this pull request? Previously in from_avro/to_avro, we override the method `simpleString` and `sql` for the string output. However, the override only affects the alias naming: ``` Project [from_avro('col, ... , (mode,PERMISSIVE)) AS from_avro(col, struct<col1:bigint,col2:double>, Map(mode -> PERMISSIVE))#11] ``` It only makes the alias name quite long: `from_avro(col, struct<col1:bigint,col2:double>, Map(mode -> PERMISSIVE))`). We should follow `from_csv`/`from_json` here, to override the method prettyName only, and we will get a clean alias name ``` ... AS from_avro(col)#11 ``` ## How was this patch tested?
