Primary Graphic not sent to SDL Core for Media Template

[renonick87]

Bug Report

Primary Graphic and text updated using Screen Manager, however only text gets updated. This bug is specific to Sync. See iOS bug for additional info smartdevicelink/sdl_ios#1152.

Reproduction Steps

1. Connect a media app, it will start on the media template
2. Change the layout to something else, like textAndGraphic
3. Change the layout back to MEDIA
4. Try to show another image.
5. The display capabilities that are returned don’t include that the primary graphic is supported, so it will fail.

Expected Behavior

Text and graphic should be updated.

Observed Behavior

Only text is updated. Screen manager somehow determines that there is no image to update.
