Fix: Avoid redundant getpresentationinfo call when startPresentation parameter is used

- Added a `_startingPresentation` flag to track the state of the presentation startup.
- Modified the `onUpdateParts` method to prevent redundant `getpresentationinfo` calls during initialization.
- Updated the presentation start logic to set the flag when the presentation begins, ensuring the request is sent only once.
