Fix PMS timeline reporting on clients when using playMedia

[jjlawren]

Description

Add missing parameters to the player playMedia command.

This fixes an issue where some AndroidTV (e.g., Nvidia Shield and Fire TV), Samsung (Tizen), LG WebOS, and likely other clients do not report timeline updates to PMS when playback is started using plexapi. This would cause active playback sessions to not show up in the Plex Web dashboard (and PlexServer.sessions()), watched states to not update, etc.
