Backup even history for manga not in the library?

[FedericoHeichou]

Describe your suggested feature

I open a feature request that was in tachiyomi.
I think it would be pretty useful because we need to migrate everything now.
It was added to 0.15.x milestone.

When we backup history in the backup options of manga, then it only backs up the history for the manga in the library and not others. Could we implement it the other way?
