Refactor SimpleViewController and SimpleView for improved mock behavior in tests

- Updated SimpleView to extend FrameLayout instead of ReactView, avoiding React surface rendering in tests.
- Enhanced method implementations in SimpleView to return appropriate values and added no-op comments for clarity.
- Cleaned up formatting in SimpleViewController for better readability.
- Removed unnecessary blank lines in TestApplication and added a newline in index.js for consistency.
