LibJS: Make Interpreter::in_strict_mode() work outside of scope

Browse source 
This one is a little weird. I don't know why it's okay for this
function to assume that there is a current scope on the scope stack
when it can be called during global object initialization etc.

For now, just make it say "we are in strict mode" when there is no
currently active scope.
