ASSERT_UNLESS_FUZZING() (which is defined multiple times!) caused problems due
when __VA_ARGS__ was empty which is most of the time. So I just disallowed the
optional string, which was only used in a small fraction of the occurrences.
I don't particularly like this patch. I'm not convinced its any better than
just removing the nsPrintfCString()s like I did earlier, but I've done it to at
least show what's involved.
