FIx embedded music player interfering gallery grid view on publicly shared folders

- The embedded music player was accidentally being loaded also on gallery share page pages (having url like .../apps/gallery/s/3WGX4zdkpdX0zyu#). There, some APIs referenced by music-file-player.js were not available, and this prevented the page from loading.
