Screen Manager - images not sent on reconnection

[NicoleYarroch]

Bug Report

When the app reconnects to a head unit during the same session, sometimes the graphics (including the blank image) uploaded by the screen manager do not get sent to Core due to the SDLUploadFileOperation not being able to get the file data. The inputStream for the SDLFile does not have any bytes available, resulting in an sdl_fileManager_fileDoesNotExistError error. Cleanup may have to be performed by the screen manager when the app disconnects from the head unit (we are not doing any cleanup now).

Reproduction Steps

1. Connect the app to the head unit and open the SDL app (iAP connection).
2. Disconnect the app from the head unit by pulling the USB cord (do not kill the app).
3. Reconnect the app to the head unit and open the SDL app.

Expected Behavior

All the graphics should upload successfully on reconnection.

Observed Behavior

Some of the graphics fail to upload successfully. A sdl_fileManager_fileDoesNotExistError error is returned.
