BranchService cache contains invalid value after index fail

[vbradnitski]

NodeStorageServiceImpl:

• version and branch records remain after index failing. (could not be a bug)
• BranchService cache doesn't evict a value for failed node path.

It is likely that after #9205 we don't need this cache. For instance if we use primary search preference and refresh.

BranchService cache represents what is stored in branch (storage) index, but not in search index - this is expected.

It is unfortunately not that easy to remove cache - as it mitigates duplicate paths problem on single server instances. #9061 (comment)

Problem with dyssynchronization between storage and search is more generic, for instance #10448 .

Closing, because described problem is not a problem - and other similar issues exist.
