Comment:

 Marking for `commit`.

 A few enhancements to Dion's patch:

 - Unit test added
 - Checks for the instance of `WP_Post` which is the expected data type if
 the post exists
 - Retains the return signature of string data type for backwards
 compatibility, documentation, etc by returning an empty string if the post
 does not exist
