Improve symbol reference detection in SymbolRefAction

- Added a function to check if the symbol at a given index is the correct symbol.
- Adjusted the getSymbolPosition function to use the new check function.
- Enhanced the findSymbolInWorkspace function to handle more edge cases.
- Added more logging for better debugging and traceability.
