Fix lookup of methods in the scope object

Commit 939014cb9cad2f3357f47b28a4580397c17b913c improved performance of
property lookups beyond the scope object, with the unfortunate
side-effect that the previously polymorphic lookup of methods broke.

Fix this by moving the handling to the caller side and falling back to
the string lookup for functions.

Fixes: QTBUG-71204
