Keeping the app in background causes it show Source Not Installed and no download buttons

[curche]

Steps to reproduce

These steps are kinda rough I know but I can't really describe it very well so sorry about that

1. Open a manga
2. keep the app in recents and switch to other apps for atleast an hour or few hours
3. Switch back to the app to land on the same manga page that you left it at

Expected behavior

the manga page is the same as you left it and you can see the source name and downloaded chapters

Actual behavior

Source shows up as unrecognized and downloaded chapters arent displayed

Likely related, leaving the app on a source and switching back after a while gives a "Source not installed" error message. It seems like sources aren't loaded properly when SY loads into a screen other than the default

Known Main Tachi issue, I would not be surprised if it was more prevalent in SY since it does a few extra things in source init, but they are needed. But the root cause is still main Tachi.

Temporary fix for downloads is to go to Advanced settings and click invalidate downloads index.
