FFI finalizers can fire in unspecified orders, but for MuPDF, we need to ensure that the context is the *very* last thing that get destroyed. As such, we need to make sure we close open documents properly on our end, first. This prevents potential crashes while switchign to USBMS inside an open document handled by MuPDF. Fix #7428
