The way that `UpgradeAdapter` needs to be setup, you often find that
you must pass a `forwardRef` for an `NgModule.import`. Pre-ivy, this
gets resolved at runtime, but until this is implemented in ivy, we can
workaround it by resolving it in the `UpgradeAdapter` upfront.
This should be backward-compatible since by the time we actually
create the dynamic `NgModule` that has the import, the imported
class should be defined.
