[api-digester] Force lazy attribute calculations as workaround
[api-digester] Force lazy attribute calculations as workaround

We were relying on attributes being propagated by the type-checker, for
example from a property to its accessors, but the goal is for these to
be caculated lazily by the request evaluator, so we should be checking
the AST predicates instead.  As a workaround, force calculating them to
cause the attributes to be added for now to fix a CI failure.
