Fixes issues when bazel is used alongside cmake (#6770)

* fixed multiple registrations

* fixed notification show for files in a different project model

* Rename .java to .kt

* changes for 243

* added read action

* created service for CLionNotificationProvider

* added psw status to simple integration test

* Revert "added psw status to simple integration test"

This reverts commit c2906ad.

Let's wait with this until we drop 241. Don't want to introduce sdk compat for tests.
