Complete Java usage tracker if analysis extension finishes (KT-27487)

In cases when kapt compiler plugin runs in stubs generation mode,
Java usage tracker was not completed. This caused issues with
the incremental compilation if Java files changed.

E.g. if a constant defined in Java source file changed, stubs
would not be recompiled because the Java usage tracker would
not report changed type. This commit fixes that issue.
