Android Auto: Fix Separator and Remove Thin Spaces

Description

This MR is a small clean-up to remove the half space from the Android Auto display subtitle and fix a separator in the track listing.

Motivation and Context

Tested VLC on a Chevy Malibu. It does not appear the head unit can render half-spaces on the GM home screen. Google also increased the font size of the 2nd line in the Android Auto UI, so it is less apparent if a full space or half space is used at this point. I believe the best solution is to simply remove the half-space to increase compatibility.
