[OLINGO-768] Delete getTarget method at EdmAnnotations interface

The method never worked. Also the design dod not allow to return all
possible target types. For example an entity type as target results in
returning the EdmEntityType object but for functions we would have to
return a list of functions. If needed we can implement another method
later.
