Title: Fixed #20488 -- Added copy and move methods to the storage API

* implemented these methods in the default FileSystemStorage
* fix issue with storage tests: each test from FileStorageTests
was run twice (when inheriting from a TestCase class all test_
methods are ran in the subclass as well)
