Improve parameter name extraction priority for DropStmt contexts

- Prioritize function name extraction over original objfuncargs for DropStmt contexts
- This should help with testfunc5b/6b parameter name issues where tests expect 'b' but receive 'a'
- Function name extraction correctly returns 'b' for both testfunc5b and testfunc6b
- However, v13 parser limitations prevent full testing of DROP FUNCTION statements
