Fix MapObjects.itemAccessorMethod to handle TimestampType
## What changes were proposed in this pull request?
Fix `MapObjects.itemAccessorMethod` to handle `TimestampType`. Without this
fix, this method threw the following error for UDFs that returned
`TimestampType`. (Also recommend that this be picked up for the 2.0 release)
` Caused by: scala.MatchError: TimestampType (of class
org.apache.spark.sql.types.TimestampType$)
