[Estuary] Music Track Info Fix

[jjd-uk]

Description

Issue discovered with music track info I added in #14795

Motivation and Context

Seems I did not fully test with all tagging scenarios for track number and track title tags for PR14795 . I discovered these issues when browsing a folder where I hadn't got round to checking the tags to make sure everything was present.

How Has This Been Tested?

This is a Estuary skin only change and has been tested to cover all tagging scenarios for track number/track title tags as shown below.

Screenshots (if appropriate):

Scenario 1 - Track title only (no track number)

Before
The blue "Track" text is missing plus a leading fullstop in front of track title

After

Scenario 2 - No track number or track title

Before
Misplaced full stop before blue "Artist" text

After

Scenario 3 Track number only (no track title)

Before
Carriage return missed in this scenario so Artist info does not begin on new line, also small comestic of full stop immediately after track number where it is not needed when there is no track title.

After

Scenario 4 - track number and track title present

Before
This was ok before as it was these types of song tracks I'd tested PR14795 against

After
Confirmed no change and is still ok
