KAFKA-5787: StoreChangelogReader needs to restore partitions that were
added post initialization
If a task fails during initialization due to a LockException, its changelog
partitions are not immediately added to the StoreChangelogReader as the thread
doesn't hold the lock. However StoreChangelogReader#restore will be called and
it sets the initialized flag. On a subsequent successfull call to initialize
the new tasks the partitions are added to the StoreChangelogReader, however as
it is already initialized these new partitions will never be restored. So the
task would remain in a non-running state forever.
