Title: currently lib/Dancer/Core/Role/Template.pm's apply_layout specifically 

allows three states: don't apply layout (undef), apply default layout (no $layout) or apply layout specified in $layout. That may not be ideal (or maybe it is?), but as long as that's the case it makes sense to allow Maybe[Str] for layout. And fixes 1 test. PS: This was already suggested in https://github.com/PerlDancer/Dancer2/pull/92, with no specific approval or rejection.
