Fix multiple 'unresolved java classifier' errors

Use the same component (NotFoundClasses) as in loading of compiled Kotlin
symbols.

Some tests were changed to avoid a diagnostic that is now reported when a
non-found class is encountered in a signature (e.g. staticMethod.1.java where
JDK seems to be not configured)
