Fix(Queue): Fix author marquee resetting every second when the artist name is too long

Calculate the max width for the queue time to prevent resetting the artist marquee's scrolling position when the artist name is longer than the space available. Without a fixed width the scrolling position is reset every second when updating the text and thus the width of queueTotalDuration.
