fix[MinecraftDownloader]: Better handling in local profile while online

This used to throw the exception at
https://github.com/AngelAuraMC/Amethyst-Android/blob/dcdcdff363090ecb2169425269447977cedd2fc3/app_pojavlauncher/src/main/java/net/kdt/pojavlaunch/Tools.java#L898-L899O

Which resulted in a confusing error box. This just triggers that but
earlier so we catch it and provide a nicer error box.
