MIOS: Fix SConfig::OnNewTitleLoad not being called

Oversight from #9545, which moved the "new game has been loaded" logic
to a separate OnNewTitleLoad function that has to be called explicitly
*after* a title has loaded.

Coupled with the commit that makes Dolphin not clobber 0x1800-0x3000
when using MIOS, this fixes Wind Waker and other MIOS-patched games
when they are launched from the System Menu.
