SCUMM: FT: DiMUSE crash when exiting "screensaver"

[criezy]

In Full Throttle, if you wait a few minutes without doing anything, you get a "screensaver" with a rotating motor vehicle. Clicking to exit that screen cases a crash.

You can get that right at the start of the game, so I am not going to attach a savegame.

ScummVM: macOS M1 (compiled by myself) current master
Game: Full Throttle French Mac version

I forgot to indicate the crash is caused by the following assert:

Assertion failed: (!filename.empty()), function open, file file.cpp, line 45.

Thanks! This was such a stupid mistake on my end, glad you found it :)
