[antlr-interest] C# target update (CL#5191) broke my tree parsers

[Sam Harwell]

In TreeParser.cs, GetCurrentInputSymbol was changed to return null, so
rules like the following don't work anymore:

 

rule

:               ^(SOMETHING (item=A | item=B) somethingElse?)

                {

                                HandleItem( item.Token ); // now throws
NullReferenceException

                }

;
