fix(downloader): dont invalidate anime downloads on startup

[Secozzi]

Closes #1296

[Sadwhy]

I frequently download things outside of the app and use it as a manager and tracker of sorts. Please make this into a toggle if you really need to. I don't want to go to the settings to invalidate downloads every time.

That's out of scope of this pr, create an issue with a feature request instead
