shouldThrowWithMessage fails with DIP1008 and the nogc package

[atilaneves]

unittest {
    import unit_threaded: shouldThrowWithMessage;
    fun.shouldThrowWithMessage("why hello there");
}


void fun() {
    import nogc: enforce;
    enforce(false, "why hello there");
}

void main() {}

The problem that it's not @safe to be able to access the msg from the super class because of lifetime reasons. The fix is to make sure to use NoGcException when catching but that reveals a new bug.
