fix #formalParametersAt: where due in Traits...
Implemented thanks to new support method in Parser

Note: this method has no senders in trunk.
I suspect it does not have much value...
I presume it could have been used by refactoring tools, but RB must be using its own parser...
Anyone knows of a package using #formalParametersAt: ?
