Dokka prints not-yet-loaded-registry warnings

[owengray-google]

Describe the bug
WARN: Attempt to load key 'java.correct.class.type.by.place.resolve.scope' for not yet loaded registry
is printed several times.
This occurs during the generating documentation models step. It appears in bugs by other developers; I do not believe it is specific to our setup. I tested it by running base dokka (not dackka) against the androidx codebase; it appeared twelve times.
This error may be coming from com.intellij.openapi.util.registry.RegistryValue.

Expected behaviour
If dokka would produce warnings that are not actionable by clients, they are suppressed (or fixed) in the library itself.

Note: this also occurs several times when running any java-source unit test in the dackka checkout.
