Title: Minor DFS refactoring

Four small changes into one:

* Consistent lookup cache request on add sub-file
* Assert on transactions, that are expected to always exist (even if inactive)
* Remove the bad ```clearFiles()``` on adding new actions or retries. That breaks ```cCreateSuperFile``` when inside user transactions
* Log error if trying to commit/rollback an inactive transaction (it's not an error, though)
