Make custom app run on start, not just when its tab is clicked

Last I checked, extensions aren't loaded in until you open the marketplace app. We want them to be loaded in on Spotify launch.

I actually think this may be part of the error in lyrics-plus 🤔 spicetify/cli#1090

@afonsojramos Nah it's an issue with this, I was super lazy lol.

It's because it activates extensions in loadPage(), which is when the app is clicked in the sidebar. Needs to be in some other place.

Just updating the issue status:

It looks like Custom Apps can't execute any code until their icon is clicked. I put a console.log('loaded') just at the top of the main index.js file and it doesn't log until you click on it in the sidebar. I think we need some sort of hook or something added to Spicetify so that custom apps are able to execute code on app start, like extensions can.

Possible solution suggested was to add a value in the CustomApp's manifest for a js file that gets run as an extension (since they can run code on app start).

This is implemented now! 🎉
