Fixed issue where Video would be skipped unintentionally in a certain scenario

Scenario: Only 1 player in a Theater Room, watching a video. Another player enters the room and Votes to Skip the video.

Issue: When the 2nd player leaves the Room, CheckVoteSkip() is called, and the Video is skipped regardless of the first player's intentions.
